radeon: Fix scissors for r600 KMS.

Browse Source 
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.
