ALSA: hda - Don't override maxbps for FLOAT sharing with linear formats

Browse Source 
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.
