[PATCH] ipc/msg: Replace testmsg with msg_matchs_type

[Nick Huang <sef1548@gmail.com>]

The function name testmsg is misleading, as its purpose is not to test a message
but to check whether a message matches the given mode and type conditions.

To more clearly convey its role in validating whether a message can be used for
send or receive operations, it has been renamed to msg_matchs_type.
