ibmvscsi: Abort init sequence during error recovery
commit 9ee755974bea2f9880e517ec985dc9dede1b3a36 upstream. 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.
