Currently, TDLS STA disconnect notification is not sent during
roam, so WMI_TDLS_SET_STATE_CMDID with disable command is not sent
to firmware. This leads to unexpected behavior in firmware when STA
have migrated to different mac based on new band (2 GHz to 5/6 GHz or
vice-versa) due to roaming, but TDLS STA remain on previous mac.
Firmware expects host to send WMI_TDLS_SET_STATE_CMDID on roam also
so that it can destroy and create new TDLS STA instance and map TDLS
STA to new mac.
To fix above issue, send WMI_TDLS_SET_STATE_CMDID with disable TDLS
state to firmware after driver receives roam sync indication which
leads to destruction of TDLS STA instance in firmware.
Host driver would later send WMI_TDLS_SET_STATE_CMDID with enable TDLS
state(not part of this commit) after successful STA roaming so that
firmware maps TDLS STA with new mac.
This change also removes unused ucfg_tdls_notify_sta_connect() and
ucfg_tdls_notify_sta_disconnect() APIs.
