Richard Weinberger 453f2dfa34 ubifs: wbuf: Don't leak kernel memory to flash 
commit 20f1431160c6b590cdc269a846fc5a448abf5b98 upstream.

Write buffers use a kmalloc()'ed buffer, they can leak
up to seven bytes of kernel memory to flash if writes are not
aligned.
So use ubifs_pad() to fill these gaps with padding bytes.
This was never a problem while scanning because the scanner logic
manually aligns node lengths and skips over these gaps.
