freedreno/a6xx: fix LRZ hang

Browse source 
In detecting the case where we actually do need to re-emit LRZ state
(due to new batch), we were checking `ctx->last.dirty` to detect when
we cannot trust previous state.  But this is cleared before we check
it.

Move where it is cleared to the end of the draw_vbo() path.

Fixes: dfa702e94b ("freedreno/a6xx: limit LRZ state emit")
