[PATCH][RESEND] SCSI, Brocade FC HBA: Remember to always release_firmware()so we don't leak memory.

From: Jesper Juhl
Date: Wed Mar 23 2011 - 19:00:51 EST


Once we've called request_firmware() we must remember to call
release_firmware() to free memory. We don't currently do this in
bfad_read_firmware(); causing a memory leak.
