scsi: qla2xxx: Simplify the functions for dumping firmware 

Instead of passing an argument to the firmware dumping functions that tells
these functions whether or not to obtain the hardware lock, obtain that
lock before calling these functions. This patch fixes the following
recently introduced C=2 build error:

  CHECK   drivers/scsi/qla2xxx/qla_tmpl.c
drivers/scsi/qla2xxx/qla_tmpl.c:1133:1: error: Expected ; at end of statement
drivers/scsi/qla2xxx/qla_tmpl.c:1133:1: error: got }
drivers/scsi/qla2xxx/qla_tmpl.h:247:0: error: Expected } at end of function
drivers/scsi/qla2xxx/qla_tmpl.h:247:0: error: got end-of-input
