drm/vc4: Handle drm_atomic_helper_swap_state failure
drm_atomic_helper_swap_state() will be changed to interruptible waiting
in the next few commits, so all drivers have to be changed to handling
failure.
VC4 has its own nonblocking modeset tracking through the vc4->async_modeset
semaphore, so it doesn't need to stall in swap_state. Pass stall = false
and BUG_ON when it returns an error. This should never happen for !stall.
