scsi: qla2xxx: Turn off target reset during issue_lip
[ Upstream commit 0b7a9fd934a68ebfc1019811b7bdc1742072ad7b ]
When user uses issue_lip to do link bounce, driver sends additional target
reset to remote device before resetting the link. The target reset would
affect other paths with active I/Os. This patch will remove the unnecessary
target reset.
