anv: remove duplicate pipe_control workaround
Commit a603cc06334f ("anv: move some pc was to
batch_emit_pipe_control_write") moved some WAs from
emit_apply_pipe_flushes() to batch_emit_pipe_control_write(), but it
turns out one of them was already there since cf7e1f3817d4 ("anv,
iris: add missing CS_STALL bit for GPGPU texture invalidation").
