disp: msm: sde: avoid duplicate fence create from client

Browse Source 
SDE fence driver avoids duplicate fence creation if
fence timeline is not increased. This may lead to issue
if client closes the fence with failure ATOMIC_COMMIT.
SDE fence driver provides the closed fd node to subsequent
valid commit and leads to invalid state. This patch avoids
duplicate fence creation from crtc and connector object
instead of sde_fence.
