drm/amdgpu: clear set_q_mode_offs when VM changed
[Why]
set_q_mode_offs don't get cleared after GPU reset, nexting SET_Q_MODE
packet to init shadow memory will be skiped, hence there has a page fault.
[How]
VM flush is needed after GPU reset, clear set_q_mode_offs when
emitting VM flush.
Fixes: 8bc75586ea01 ("drm/amdgpu: workaround to avoid SET_Q_MODE packets v2")
