mailbox: Stop using ENOSYS for anything other than unimplemented syscalls 

In accordance with e15f431fe2 ("errno.h: Improve ENOSYS's comment") and
91c9afaf97 ("checkpatch.pl: new instances of ENOSYS are errors") we're
converting from the old meaning of: ENOSYS "Function not implemented" to
a more standard EINVAL.
