[SCSI] qla4xxx: Use IDC_CTRL bit1 directly instead of AF_83XX_NO_FWDUMP flag.
Removed AF_83XX_NO_FWDUMP flag and directly checking IDC_CTRL bit1 while taking minidump, to check for graceful reset. Signed-off-by: Vikas Chaudhary <vikas.chaudhary@qlogic.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
