qcacld-3.0: De-initialize idle timer on tdls peer reset

Currently idle timer does not gets de-initialize on tdls peer
reset because of which there could be a possibility that in
case of multiple tdls connection and disconnection with multiple
peers, this timer might get assigned and re-assigned to different
peers which may lead to an issue where this timer never gets
started for the required peer.

In current scenario whenever the first TDLS connection
(Peer a with sta_idx 0) happens, tdls peer idle timer object is
initialized with “&tdls_soc->tdls_conn_info[0];”.
Now if this peer a gets disconnected and peer b gets connected
and peer gets the same sta_idx 0, then peer will be associated
with timer “&tdls_soc->tdls_conn_info[0];”,hence 2 timer init
happens with the same sta_idx for peer a and peer b.
(here peer a is in disconnected state and peer b is in connected
state)

Now if peer a gets connected it will get the sta_idx 1, as timer
initialization is already done for peer a with sta index 0 so
timer initialization will not be done again.
Now if peer b gets disconnected it will set the tdls_info for
sta_idx 0 to invalid (INVALID_TDLS_PEER_INDEX).
Now for peer a timer will be started and when timer expires in
timer handler function “tdls_ct_idle_handler” will not be invoked
as sta_idx is already set to INVALID_TDLS_PEER_INDEX.

To address above issue, de-initialize the idle timer for tdls
peer on every tdls peer reset.
