Mark Nelson 302378534c [SCSI] ipr: fix lockdep warning from ipr_ioa_reset_done 
To fix the following lockdep warning we turn the spin_unlock_irq() into
a spin_unlock() and similarly for the corresponding spin_lock_irq(). We
can do this because there is no need to enable interrupts in this path
(thanks to Bring King for the tip).

Badness at kernel/lockdep.c:2193
