Remove unnecessary block structure around CONTROL_PING messages.

Now that the M() and S() macros accept a message parameter, there
is no longer a need to introduce a new block structure around the
CONTROL_PING messages just to have a new unbound "mp" variable.
Instead, just use one named "mp_ping" directly.
