ALSA: pcm: Unify ioctl functions for playback and capture streams

Browse source

Some ioctl functions are implemented individually for both playback
and capture streams although most of the codes are identical with just
a few different stream-specific function calls.  This patch unifies
these places, removes the superfluous trivial check and flattens the
call paths as a cleanup.  Meanwhile, for better readability, some
codes (e.g. xfer ioctls or forward/rewind ioctls) are factored out as
functions.
