Orinoco is a PIO-only ISA/PCMCIA 802.11b device with extra bus interface
connections for PCI/Cardbus/mini-PCI and a few pre-2002 Apple PowerMac
variants. It supports both wireless extensions and CFG80211, but I could
not tell if it requires using both.
This device used to be one of the most common ones 20 years ago, but
has been orphaned for most of the time since then, and the conversion
to cfg80211 has stalled in 2010.

There is currently no return check for writing an authentication
type (HERMES_AUTH_SHARED_KEY or HERMES_AUTH_OPEN). It looks like
it was accidentally skipped.
This patch adds a return check similar to the other checks in
__orinoco_hw_setup_enc() for hermes_write_wordrec().
Detected using the static analysis tool - Svace.

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring array fields.
Validate the expected key size and introduce a wrapping structure
to use as the multi-field memcpy() destination so that overflows
can be correctly detected.

ezusb_read_ltv() is always invoked via the ->read_ltv() callback. This
callback is mostly invoked under orinoco_lock() which disables BH.
There are a few invocations during probe which occur in preemptible
context via:
ezusb_probe() -> orinoco_init() -> determine_fw_capabilities()
Extend `hermes_ops' with the ->read_ltv_pr callback which is implemented
with the same callback like ->read_ltv on `hermes_ops_local'.
On `ezusb_ops' ->read_ltv is used for callbacks under the lock which
need to poll.
The new ->read_ltv_pr() is used in the preemptible context in which it
is possible to wait for the completion. Provide HERMES_READ_RECORD_PR()
and hermes_read_wordrec_pr() which behave like their non _pr equivalents
and invoke ->read_ltv_pr().
This removes the last user of ezusb_req_ctx_wait() and can now be
removed.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.
