thunderbolt: Fix a logic error in wake on connect
[ Upstream commit 1a760d10ded372d113a0410c42be246315bbc2ff ]
commit a5cfc9d65879c ("thunderbolt: Add wake on connect/disconnect
on USB4 ports") introduced a sysfs file to control wake up policy
for a given USB4 port that defaulted to disabled.
However when testing commit 4bfeea6ec1c02 ("thunderbolt: Use wake
on connect and disconnect over suspend") I found that it was working
even without making changes to the power/wakeup file (which defaults
to disabled). This is because of a logic error doing a bitwise or
of the wake-on-connect flag with device_may_wakeup() which should
have been a logical AND.
Adjust the logic so that policy is only applied when wakeup is
actually enabled.
