iris: Use u_default_clear_buffer

iris uses u_default_buffer_subdata for buffer uploads via a CPU map so
clearing shouldn't be substantially worse.  We can do it with BLORP in
the future if we decide it's useful.

[Alyssa: A BLORP implementation is available at
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15931 however nobody
has taken to reviewing that solution.]
