[PATCH] drm/amd/amdgpu/amdgpu_ring: match type used for loop counting

[Joshua Peisach <itzswirlz2020@xxxxxxxxxxx>]

The argument passed to _insert_nop is a uint32_t, and the loop
counts to a regular integer. In the event of the argument being
larger than the maximum integer size, the regular integer would
become negative, and never reach the count number.

So, match the type to prevent an infinite loop.
