crypto: ux500 - Fix kmap() bug
Once the crypto hash walk is started by crypto_hash_walk_first()
returning non-zero, crypto_hash_walk_done() must be called to unmap any
memory which was mapped by *_walk_first().
Ensure crypto_hash_walk_done() is called properly by:
1) Re-arranging the check for device data to be prior to calling
*_walk_first()
2) on error call crypto_hash_walk_done() with an error code to
allow the hash walk code to clean up.
While we are at it clean up the 'out' label to be more meaningful.
