scsi: ufs: fix spinlock recursion
spin_lock_irq() / spin_unlock_irq() is used so interrupts are
enabled after unlocking the spinlock. However, it is not guaranteed
they were enabled before.
This change uses the proper irqsave / irqrestore variants instead.
Without it, a spinlock recursion on the scsi request completion path
is possible if completion interrupt occurs.
