x86_64: fix msg size forwarding in case it's not set by userspace
* ipc/copy_user.c: recent MIG stubs should always fill the size
correctly in the msg header, but we shouldn't rely on that. Instead,
we use the size that was correctly copied-in, overwriting the value
in the header. This is already done by the 32-bit copyinmsg(), and
was missing in the 64-bit version.
Furthermore, the assertion about user/kernel size make sense with
and without USER32, so take it out if the #ifdef.
