[PATCH net] ibmvnic: continue fatal error reset after passive init

Commit f9c6cea0b385 ("ibmvnic: Skip fatal error reset after passive init")
says "If the passive
CRQ initialization occurs before the FATAL reset task is processed,
the FATAL error reset task would try to access a CRQ message queue
that was freed, causing an oops. The problem may be most likely to
occur during DLPAR add vNIC with a non-default MTU, because the DLPAR
process will automatically issue a change MTU request.
Fix this by not processing fatal error reset if CRQ is passively
initialized after client-driven CRQ initialization fails."

Even with this commit, we still see similar kernel crashes. In order
to completely solve this problem, we'd better continue the fatal error
reset, capture the kernel crash, and try to fix it from that end.
