mp3, flac: check for seek command after decoder_read()

When we introduced decoder_read(), we added code which aborts the read
operation when a decoder command arrives.  Several plugins however did
not expect that when they were converted to decoder_read().  Add
proper checks to the mp3 and flac decoder plugins.
