ibmvnic: initialize rc before completing wait

Browse source 
We should initialize ->init_done_rc before calling complete(). Otherwise
the waiting thread may see ->init_done_rc as 0 before we have updated it
and may assume that the CRQ was successful.

Fixes: 6b278c0cb3 ("ibmvnic delay complete()")
