overlay: Reset allocation on all pipes, if commit fails.
If commit fails on a pipe, overlay hal needs to reset allocation
on all pipes for the given display. As MDP Comp fails, it falls
back to video and PipeBook logic does not pick-up those pipes on
which commit was successful. Driver sets new pipes and un-stages
previously set pipes (with same z-order). Pipe clean-up happens
and then in next round, PipeBook logic picks-up previous pipes
hence userspcae and driver remain out of sync.
