wlan: Revert back changes setting the gLimRspReqd for stats requests

The link speed is showing as 0 in the display as the function
limProcessNormalHddMsg(pMac, limMsg, false) is being
called with fRspReqd as false for eWNI_SME_STA_STAT_REQ.

Changes are made to revert back freeing the request when fRspReqd
is false in functions __limProcessSmeGetStatisticsRequest,
__limProcessSmeGetRoamRssiRequest and __limProcessSmeStatsRequest.

ASoC: msm: Reset the stream open flag after CMD_CLOSE is sent to DSP

In case of gapless playback, driver does not wait for EOS. CMD_CLOSE
for stream one or two can be called from compress driver free before
EOS ACK for stream one is received. This can result in CMD_CLOSE to
be sent for already closed stream. Reset the stream open flag after
CMD_CLOSE is sent to DSP to prevent multiple CMD_CLOSE on same
stream.

ASoC: msm: ensure check before accessing session private data.

The compressed session needs to be active to set volume to dsp.
Ensure the check to see valid session exist before accessing
private data, else results in kernel panic.

The Memory allocation for driver data also needs to be freed
for failure in session open.

ASoC: compr: Disable soft-pause for compress playback

Soft-pause (i.e pause ack after a timeout) adversely affects
audio/video sync during pause/resume use cases leading to some
frame drops. Disable this feature for compress playback.

wcnss: Configure WLAN MAC addr through user control interface

thru module parameters from wcnss service, however that required the
wcnss userspace daemon to have the root permission.

stereo call recording support

Patch that allows for call recording in
stereo (left channel: TX; right channel:
RX). Tested on Nexus 5 (MSM8974). Likely
works on other recent MSM chipsets as
well.
