Ramkumar Radhakrishnan 73f952ae3f gralloc: Override gralloc calculated size only if bufferSize is greater.
bufferSize set using native window set buffer size will override gralloc
calculated size only if bufferSize is greater.
Fix for 720P, 1080P HD content playback is not working on 7x27A due to
buffer size mismatch between requested size by frameworks and allocated
size by gralloc for HAL_PIXEL_FORMAT_YCrCb_420_SP and
HAL_PIXEL_FORMAT_YCrCb_420_SP format
