moved expression to audioFormatSizeToTime()

The multi-line expression which calculates sizeToTime is hard to read, partly because "cb->audioFormat." is too long. Create a separate inline function in audio.h for that. git-svn-id: https://svn.musicpd.org/mpd/trunk@7277 09075e82-0dd4-0310-85a5-a0d7c8717e4f
