Currently, the avail IOCTL doesn't pass any error status, which means typically on error it simply shows no data available. This can lead to situations where user-space is waiting indefinitely for data that will never come as the DSP has suffered an unrecoverable error. Add snd_compr_stop_error which end drivers can call to indicate the stream has suffered an unrecoverable error and stop it. The avail and poll IOCTLs are then updated to report if the stream is in an error state to user-space. Allowing the error to propagate out. Processing of the actual snd_compr_stop needs to be deferred to a worker thread as the end driver may detect the errors during an existing operation callback.
