alsa: various improvements

Browse source 
Remove some magic constants that are not needed anymore with the
headroom.
Clamp the error to some reasonable value so that we don't adjust the
rate too much but still apply all of the correction calculated by the
dll.
Remove the bandwidth adjustment.
Also update the matching and resample fields when we reassign the
node to a new driver. This could cause the new follower to not activate
the adaptive resampler and get out of sync.
