[ALSA] ad1848: simplify MCE down code

The polling loop to check for ACI to go down was more convoluted than it
needed to be.  New loop should be more efficient and it is a lot simpler.  The
old loop checked for a timeout before checking for ACI down, which could
result in an erroneous timeout.  It's only a failure if the timeout expires
_and_ ACI is still high.  There is nothing wrong with the timeout expiring
while the task is sleeping if ACI went low.
A polling loop to check for the device to leaving INIT mode is removed.  The
device must have already left init for the previous ACI loop to have finished.
