dmaengine: at_xdmac: remove a stray bottom half unlock

Browse Source 
[ Upstream commit 0b515abb6b ]

We switched this code from spin_lock_bh() to vanilla spin_lock() but
there was one stray spin_unlock_bh() that was overlooked.  This
patch converts it to spin_unlock() as well.

Fixes: d8570d018f ("dmaengine: at_xdmac: move spin_lock_bh to spin_lock in tasklet")
