P2P: Cancel group formation timeout on group removal (on client)

P2P: Cancel group formation timeout on group removal (on client)

Group formation timeout is normally canceled when 4-way handshake is
completed (WPA_COMPLETED -> wpas_p2p_completed). However, it is possible
for the GO to stop the group before this happens (i.e., send
Deauthentication frame with reason code 3 before 4-way handshake is
completed). This resulted in the group getting removed, but the group
formation timeout left behind. The unexpected timeout may then result in
undesired termination of the following operation. Fix this by canceling
the group formation timeout in wpas_p2p_group_delete() similarly to how
group idle timeout was canceled there.
