From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currenly the error check on variable instance is always false because
it is a uint32_t type and this is never less than zero. Fix this by
making it an int type.
Addresses-Coverity: ("Unsigned compared against 0")
Fixes: 7d0e6329dfdc ("drm/amdgpu: update more sdma instances irq support")
