[SCSI] bfa: dereferencing freed memory in bfad_im_probe()
If bfad_thread_workq(bfad) was not BFA_STATUS_OK then we freed "im"
and then dereferenced it.
I did a little clean up because it seemed nicer to return directly
instead of doing a superfluous goto. I looked at other functions in
this file and it seems like returning directly is standard.
