[PATCH] 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. Signed-off-by: Mateusz Guzik Reported-by: Gabriellla Schmidt Cc
