ipc: fix compat msgrcv with negative msgtyp
commit e7ca2552369c1dfe0216c626baf82c3d83ec36bb upstream.
Compat function takes msgtyp argument as u32 and passes it down to
do_msgrcv which results in casting to long, thus the sign is lost and we
get a big positive number instead.
Cast the argument to signed type before passing it down.
