ASoC: msm: Fix the issue that freed data structure is accessed

When there is a failure while opening q6asm capturing stream,
it releases the q6asm data structure which is accessed by
stream closing function and lead to a crash. Resolving the
issue by freeing the data structure in closing function
instead of during opening failure.
