[SCSI] qla2xxx: Drop acquisition of hardware_lock during flash manipulations.

There's no need given, I/O has been quiesced, RISC
interrupts have been disabled, and finally the RISC has been
paused.  Flash manipulation on ISP21xx, ISP22xx, and ISP23xx
parts requires the RISC to go through a full reset to
recover.
