Ramkumar Radhakrishnan 87a1cd1c88 hwc: Reset pipebook format to avoid pipe allocation failures. 
Reset format type to FORMAT_NONE to select the pipe irrespective of
the format specifed by the client. This is required for the device
where SMP starvation is unlikely, we need not keep track of formats
programmed in the pipes to avoid potential pipe crunching.
