crypto: hash - Zap unaligned buffers
Some unaligned buffers on the stack weren't zapped properly which
may cause secret data to be leaked. This patch fixes them by doing
a zero memset.
It is also possible for us to place random kernel stack contents
in the digest buffer if a digest operation fails. This is fixed
by only copying if the operation succeeded.
