mtip32xx: Use plain spinlock for 'cmd_issue_lock'
'cmd_issue_lock' is for only acquiring a free slot, and it is not used in interrupt context. So replaced irq version with non-irq version of spinlock. Signed-off-by: Asai Thambi S P <asamymuthupa@micron.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
