Igor Artemiev dc628571cf drm/radeon/r600_cs: Fix possible int overflow in r600_packet3_check() ...

[ Upstream commit a1e2da6a5072f8abe5b0feaa91a5bcd9dc544a04 ]

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.
