UBIFS: small amendments in the LEB scanning code
This patch fixes few minor things I've spotted while going through code: 1. Better document return codes 2. If 'ubifs_scan_a_node()' returns some thing we do not expect, treat this as an error. 3. Try to do recovery only when 'ubifs_scan()' returns %-EUCLEAN, not on any error. 4. If empty space starts at a non-aligned address, print a message.
