drivers: scmi-msg: handle invalid channels

Changes implementation channel_to_smt_hdr() of SMT message management
in scmi-msg driver to support being called with invalid channel ID
to relax implementation. On contrary, scmi_smt_init_agent_channel()
is expected to be called only for valid SMT channels.

By the way, with this change, scmi_entry_smt() read SMT header status
from shared memory after channel in successfully claimed, not before.
The change does not affect the communication and makes the implementation
more consistent. For consistency, I also rename local variables chan to
channel to be more explicit.
