In commit 052189a2ec95 ("dm: remove superfluous irq disablement in
dm_request_fn") the spin_lock_irq() was replaced with spin_lock() + a
check for disabled interrupts. Later the locking part was removed in
commit 2eb6e1e3aa87 ("dm: submit stacked requests in irq enabled
context") but the BUG_ON() check remained.
Since the original purpose for the "are-irqs-off" check is gone (the
->queue_lock has been removed) remove it.
