Subject: [PATCH AUTOSEL 4.14 1/3] scsi: target: core: Fix warning on RT kernels

From: Maurizio Lombardi <mlombard@...hat.com>

[ Upstream commit 84ed64b1a7a7fcd507598dee7708c1f225123711 ]

Calling spin_lock_irqsave() does not disable the interrupts on realtime
kernels, remove the warning and replace assert_spin_locked() with
lockdep_assert_held().
