[patch 11/15] zfcp: Fix abort handler for completions in progress

From: Christof Schmitt <christof.schmitt@de.ibm.com>

When the abort handler cannot find a pending FSF request, the request
completion could just be running. This means we cannot return SUCCESS,
since this would lead to call to scsi_done after exiting the SCSI
error handler which is not allowed.
