[PATCH 1/2] ibmvscsi: Abort init sequence during error recovery

[PATCH 1/2] ibmvscsi: Abort init sequence during error recovery

[Brian King]

If a CRQ reset is triggered for some reason while in the middle
of performing VSCSI adapter initialization, we don't want to
call the done function for the initialization MAD commands as
this will only result in two threads attempting initialization
at the same time, resulting in failures.
