dw3000_stm: uninterruptedly wait for pending_work to complete
Data assigned to stm->generic_work can be a local variable (e.g.:
dw3000_state_start) that discarded after function returns, and in this
case, dw3000_event_thread will get an invalid generic_work that causes
data abort.
To fix it, repeats the wait_event_interruptible_locked_irq until the
event condition meets, that is, ignore the signal interrupting case.
