This call needs to be done with interrupts enabled. So unlock and relock around this call. This is safe because: 1) the provider will do nothing with this endpoint until the iwcm either accepts or rejects. 2) the lock is only released after the iwcm state is changed, so an errant iwcm app that is destroying -and- rejecting the connection concurrently will get a failure on one of the calls.
