radeon: fix bad state emission causes kernel to do bad depth clear

The kernel lets you clear depth without getting a depth offset
from userspace, mesa used to emit state before clear, but that got
lost in the refactoring, which made the kernel bug show up. Fix
mesa driver to emit the state properly now.
