Fix *LoadModeFile not reporting errors when parsing EDID files. Fix another "RMA allocation failed" bug with audio format processing.

Detail:
  c/ScrModes - Fix loadedid() not returning errors from parseedid()
  c/ScrModes - Fix bad use of realloc() in add_audio_format() - if audio_format_count hits zero then it's expected for realloc to return NULL.
Admin:
  Tested on iMx6
