[SCSI] be2iscsi: fix boot hang due to interrupts not getting rearmed
This patch fixes a bug where the interrupts were not rearmed if the Interrupt Mask was enabled. This patch checks for Interrupt mask enabled and still rearms interrupt generation even if the Interrupt mask was enabled Signed-off-by: Jayamohan Kallickal <jayamohan.kallickal@emulex.com> Signed-off-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
