qcacmn: Deinit tx desc pool before freeing the pool

Currently when the last tx descriptor in any descriptor
pool is freed, it will also free that particular tx
descriptor pool. But before freeing the tx descriptor
pool, the pool is not marked as inactive.
Due to this, the next time when the tx descriptor pool
is tried to be allocated, since its not inactive, the same
pool is reattached, but without any memory allocated.

Deinitialize the tx desc pool before freeing it, to make
sure that the tx descriptor pool status is marked as
inactive when the decriptor pool memory is freed.
