anv: fix dynamic state emission

anv: fix dynamic state emission

The problem is that we missed looking at pipeline changes. Pipelines
hold bits of dynamic states and when it changes we might need to
reemit a packet.

v2: fix comment (Tapani)
    Add missing anv_cmd_buffer_needs_dynamic_state() use (Tapani)
