ALSA: ctxfi: Fix memory leakage when clearing DAO input mappers

Commit e576e7843c0d ("ALSA: ctxfi: Simplify dao clear {left,right} input() functions") centralized the DAO input mapper clearing logic in dao clear input(), but omitted the kfree() calls.

It removes the mapper entries from the list and sets their pointers to NULL without freeing the allocated array. This leaks memory each time dao clear input() is called.

Store the base pointer of the allocation before clearing the mapper entries and free the array after removing entries from the list.
