ALSA: hda: cs35l41: Cleanup and fix double free in firmware request

Browse source

There is an unlikely but possible double free when loading firmware,
and a missing free calls if a firmware is successfully requested but
the coefficient file request fails, leading to the fallback firmware
request occurring without clearing the previously loaded firmware.
