[PATCH 1/2] alsa-lib: fixed coverity reported issues under "USE_AFTER_FREE" checker.

[sudarshan.bisht@nokia.com]

From: Sudarshan Bisht <sudarshan.bisht@nokia.com>

Coverity Static Analysis helps developers find hard-to-spot,
yet potentially crash-causing defects early in the development phase,
reducing the cost,time, and risk of software errors.

This patch has fixes for 1) a junk assignment and 2) memory freed at wrong location.
