scsi: target: fix __transport_register_session locking
[ Upstream commit 6a64f6e1591322beb8ce16e952a53582caf2a15c ]
When __transport_register_session is called from transport_register_session
irqs will already have been disabled, so we do not want the unlock irq call
to enable them until the higher level has done the final
spin_unlock_irqrestore/ spin_unlock_irq.
This has __transport_register_session use the save/restore call.
