ARM: PL08x: fix missed spin-unlock in pl08x_issue_pending()
pl08x_issue_pending() returns with the spinlock locked and interrupts
disabled if the channel is waiting for a physical DMA to become free.
This is wrong - especially as pl08x_issue_pending() is an API function
as it leads to deadlocks. Fix it to always return with the spinlock
unlocked.
