Ramakrishna Prasad N b942708b15 libhwcomposer: Wait for framebuffer post complete before releasing composition buffers on bypass failure.
When bypass fails, MDP keeps reading the last submitted buffers until
the next VSYNC i.e., until PAN_DISPLAY is called on framebuffer. So
the previous buffers can be released only after PAN_DISPLAY IOCTL
call returns.
