Mateusz Guzik e7ca255236 ipc: fix compat msgrcv with negative msgtyp ...

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.
