Julia Cartwright beaf445bdd md/raid5: make use of spin_lock_irq over local_irq_disable + spin_lock ...

[ Upstream commit 3d05f3aed5 ]

On mainline, there is no functional difference, just less code, and
symmetric lock/unlock paths.

On PREEMPT_RT builds, this fixes the following warning, seen by
Alexander GQ Gerasiov, due to the sleeping nature of spinlocks.

   BUG: sleeping function called from invalid context at kernel/locking/rtmutex.c:993
