[PATCH][next] drm/amd/amdgpu: remove redundant assignment to variable res

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Variable res is being initialized with a value that is never read
and res is being re-assigned a little later on. The assignment is
redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
