qcacmn: Remove dp_tx_pdev_detach API

dp_tx_pdev_detach API takes care of flushing
tx descriptors and multicast enhancement mem
cleanup

dp_pdev_deinit takes care of cleaning up the
above actions and dp_tx_pdev_detach is simply
a redundant piece of code

Hence remove dp_tx_pdev_detach API and call
dp_tx_desc_flush directly from dp_pdev_deinit
