qcacld-3.0: Release TDLS del sta serialization command

After sending the wmi_peer_delete command to FW. If there
is a change in channel info of HT cap from connected AP.
Then TDLS peers in lim will be deleted and dph entry will be
freed.
While processing the tdls del sta response from FW
if dph entry is NULL then WLAN_SER_CMD_TDLS_DEL_PEER is
not released and that can lead to active command timeout.

Release the serialization command in case of NULL dph entry.
