radeon / r200: Remove unused 'dostate' parameter

radeon / r200: Remove unused 'dostate' parameter

This parameter hasn't been used since January 2010 (commit 29e02c7).
Fixes the following warning in both radeon and r200:

radeon_common.c: In function 'r200_rcommonBeginBatch':
radeon_common.c:762:14: warning: unused parameter 'dostate' [-Wunused-parameter]

Note that now BEGIN_BATCH and BEGIN_PATCH_NO_AUTOSTATE are identical.
