intel: Reserve enough space to finish occlusion queries on Gen6.

After realizing that brw_finish_batch emitted some final PIPE_CONTROLs
to record occlusion queries, Chris noted that we probably hadn't
reserved enough space to actually emit them.

Reserving a full 60 bytes seems a bit harsh, since we only need that
much if occlusion queries are actually active.  Plus, 28 bytes would be
sufficient for Gen7, and 24 for Gen4-5.

We could optimize this in the future, but it doesn't seem too critical.

intel: Move finish_batch() call before MI_BATCH_BUFFER_END and padding.

On Gen4+, brw_finish_batch() calls brw_emit_query_end(), which emits
some extra PIPE_CONTROLs to capture the current occlusion query data.
Unfortunately, it was being called *after* _intel_batchbuffer_flush
added the MI_BATCH_BUFFER_END, meaning those PIPE_CONTROLs didn't get
inside the batch.

Not only does this likely cause bogus occlusion query values, it can
also cause crashes: with the recent change to use 64-bit depth count
writes on Gen6+, we started emitting an odd-length PIPE_CONTROL, which
happened after the MI_NOOP padding.  This resulted in an odd-length
batch buffer, which resulted in execbuf2 returning -EINVAL and the
application dying with an intel_do_flush_locked failure.

On older generations, finish_batch() doesn't emit any state, so this
change shouldn't have any effect.

Huge thanks to Chris Wilson for helping me figure this out.

softpipe: fix softpipe_delete_fs_state() failed assertion

The var!=softpipe->fs_variant assertion was failing because we weren't

Since softpipe->fs_variant depends on the current fs, it's of no use
