Bluetooth: hci_mrvl: Fix wrong return value check of wait_on_bit_timeout()

Browse source

wait_on_bit_timeout() returns 0 if the bit was cleared, -EINTR if the
process received a signal and the mode permitted wake up on that signal,
or -EAGAIN if the timeout elapsed.  It never returns 1.

Hence the check "err == 1" in mrvl_load_firmware() is dead code: when
the waiting task is interrupted by a signal (-EINTR), the code falls
into the "else if (err)" branch and misreports it as "Firmware request
timeout" with -ETIMEDOUT instead of propagating -EINTR.

Fix this by testing for -EINTR so that an interrupted firmware load is
properly detected and reported.
