msm_fb: HACK: Fix MSMFB_DISPLAY_COMMIT ioctl mismatch

This is a dirty hack to get around MSMFB_DISPLAY_COMMIT ioctl not matching between display HAL and kernel. I'm not sure why they're not matching (maybe I just need to rebuild the ROM). Display HAL is sending command 0x40a46da4 for MSMFB_DISPLAY_COMMIT, so emulate MSMFB_DISPLAY_COMMIT when 0x40a46da4 command is sent.
