SDE IRQ callback can run in parallel thread to modeset after removing pp_done wait before pre_modeset. If cur_master is cleared in encoder enable function and irq callback is triggered at the same time, the irq callback could not be handled properly as cur_master is NULL. So remove clearing cur_master in encoder enable function to avoid the race condition between modeset and irq callback.
