PadMessageHandler: early return to reduce code depth. 

Get rid of an else branch to simplify code layout. No functional changes at all.

==============

This series is an attempt to reduce the control structure depth of the code
base, maintaining at the same time its exact same behaviour, bugs included. It
is, in a sense, an initial attempt at a refactoring in the spirit of its
original definition [0].

The idea beyond this refactoring is that reducing the code depth and, sometimes,
inverting some conditions, bugs and logic errors may become easier to spot, and
the code easier to read.

When looked at ignoring whitespace changes, all of these diffs should appear
trivial.
