ALSA: hda - Don't override maxbps for FLOAT sharing with linear formats
When FLOAT PCM format is available but together with other linear PCM formats, don't override maxbps value. For FLOAT format, it's always 32, thus it can be better checked in snd_hda_calc_stream_format(). Otherwise the maxbps 32 might be used wrongly even if the linear PCM doesn't support it.
