The driver reads a value from hfa384x_from_bap(), which may fail,
and then assigns the value to a local variable. gcc detects that
in in the failure case, the 'rlen' variable now contains
uninitialized data:
In file included from ../drivers/net/wireless/intersil/hostap/hostap_pci.c:220:0:
drivers/net/wireless/intersil/hostap/hostap_hw.c: In function 'hfa384x_get_rid':
drivers/net/wireless/intersil/hostap/hostap_hw.c:842:5: warning: 'rec' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (le16_to_cpu(rec.len) == 0) {
This restructures the function as suggested by Russell King, to
make it more readable and get more reliable error handling, by
handling each failure mode using a goto.

prism54 checks for dma mapping errors by comparison returned address
with zero, while pci_dma_mapping_error() should be used.

This code was supposed to trigger a BUG() if we truncate the output but
it's off by one so it allows one character to be truncated. Really
drivers shouldn't call BUG_ON() and especially for something minor like
this so I've changed it to a WARN_ON().

The current code returns success if prism2_init_local_data() fails, but
we want to return an error code. Also we can remove the bogus
ret initializer because it is wrong and never used.
