* src/coremutex.c, src/coremutexseize.c, src/coremutexsurrender.c,
inline/rtems/score/coremutex.inl: The per thread field resource_count
should only be manipulated when a mutex is priority ceiling or
priority inherit. This was reported by Chris Johns <ccj@acm.org>
who also noticed that the use of switches for all disciplines
generated less efficient code than using explicit tests for the one
or two cases we were really interested in. Further review of his
modifications made it apparent that the "isa" methods to test mutex
discipline were not being used so this modification was swept into
the code as well.
