econet: 4 byte infoleak to the network

commit 67c5c6cb8129c595f21e88254a3fc6b3b841ae8e upstream.

struct aunhdr has 4 padding bytes between 'pad' and 'handle' fields on
x86_64.  These bytes are not initialized in the variable 'ah' before
sending 'ah' to the network.  This leads to 4 bytes kernel stack
infoleak.

This bug was introduced before the git epoch.
