sfxge(4): use correct port number in sensor decoding

The port mask used for per-port sensors in mcdi_sensor_map
assumes zero-based port numbering. The port mask used in
the code is based on the one-based MCDI port number.

Fix this to lookup the correct per-port sensors, and to
allow reporting of sensor events from higher port numbers.

sfxge: add prefast annotation to common code return types

Using a typedef for common code return types (rather than "int")
allows the Prefast static analyser to understand when a function
has been successful (and thus when its postconditions must hold).

This greatly reduces then number of false positives reported by
prefast for error paths in common code functions.
