[PATCH] Fix compiler warning (unused variable)

[Luca Tettamanti]

The variable 'info' is used inside BEGIN_BATCH macro only when
XF86DRM_MODE is defined. When KMS support is not present the variable is
not used and this causes many warnings (especially in r6xx_accel.c).
This patch changes BEGIN_BATCH and similar macros to evaluate the
variable suppressing the warning.
