radeonsi: attempt to disable dcc with PIPE_HANDLE_USAGE_FRAMEBUFFER_WRITE too

Previously, we attempted to disable dcc anytime PIPE_HANDLE_USAGE_WRITE was set. That recently changed, and that caused some gbm map tests to regress on CrOS.

Fixes: 8ad12c ("gallium: rework PIPE_HANDLE_USAGE_* flags")

For reference, the failing test is here:

CHECK failed in test_gem_map_format() gbmtest.c:979

Here are the revelent gbm backends:
