drm/radeon/r100: Fix integer overflow issues in r100_cs_track_check()
It may be possible, albeit unlikely, to encounter integer overflow
during the multiplication of several unsigned int variables, the
result being assigned to a variable 'size' of wider type.
Prevent this potential behaviour by converting one of the multiples
to unsigned long.
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
