Igor Artemiev 6078d3ca13 drm/radeon/r600_cs: Fix possible int overflow in r600_packet3_check() 
[ Upstream commit a1e2da6a50 ]

It is possible, although unlikely, that an integer overflow will occur
when the result of radeon_get_ib_value() is shifted to the 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.
