drm/radeon/r600_cs: Fix possible int overflows in r600_cs_check_reg()
While improbable, there may be a chance of hitting integer
overflow when the result of radeon_get_ib_value() gets shifted
left.
Avoid it by casting one of the operands to larger data type (u64).
Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.
