ALSA: Fix memory leak on error in snd_compr_set_params()

If copy_from_user() does not return 0 we'll leak the memory we
allocated for 'params' when that variable goes out of scope.

Also a small CodingStyle cleanup: Use braces on both branches of
if/else when one branch needs it.

ALSA: core: Add support to handle compressed audio IOCTLs for capture

This is needed to support the compressed audio capture so that the

compress: change header include path

Compatibility with userspace compilation is improved if
compress_params.h is included from the same directory,
rather than relying on search paths.

ASoC: msm: Modify min and max period bytes and num periods

Modify min and max period bytes and number of periods in
compressed driver so as to be consistent with lpa and to
meet ION memory requirements. This avoids using huge

ASoC: msm: implement drain command in compress platform driver

Currently, at the end of compress audio playback, session is
terminated without ensuring compressed audio stream is completely
rendered. Use ioctl drain to drain out all the data before EOS is
signalled and session is closed. This is to make sure all the
data is played out by DSP.

ASoC: msm: Register restart api for under run issue.

Update compressed platform driver to register an restart callback.
Implementation of the restart callback is to issue an pending buffer
Written by application to restart the session when  the de queue
Process is stopped due to underrun issue.

Restart callback is triggered from the ALSA core framework when
Framework detects that the render stopped pulling the data
And application is writtig the data.

This callback will be running in atomic context.
