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

Browse source

Commit e576e7843c ("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.
