scsi: target: core: Fix warning on realtime kernels
On realtime kernels, spin_lock_irq*(spinlock_t) do not disable the
interrupts, a call to irqs_disabled() will return false thus firing a
warning in __transport_wait_for_tasks().
Remove the warning and also replace assert_spin_locked() with
lockdep_assert_held()
