    radeon: Fix scissors for r600 KMS.

    Radeon generic scissors code had problem that some of code was using exclusive
    and some inclusive bottom right corner. Only r600 driver is using exclusive
    coordinate so changed generic code to pass inclusive coordinate and r600 driver
    changes BR coordinate to be exclusive.
