sys/dshowdecwrapper/gstdshowaudiodec.c: Flip mpeg1/mpeg2 arrays for mpeg audio. Detect which type the audio is correc...

Browse source 
Original commit message from CVS:
* sys/dshowdecwrapper/gstdshowaudiodec.c:
Flip mpeg1/mpeg2 arrays for mpeg audio. Detect which type the audio
is correctly, instead of backwards. No functional changes, since this
mistake was completely self-consistent.
