Subject: [PATCH][next] drm/amd/powerplay: remove a less than zero uint32_t check

From: Colin Ian King <colin.king at canonical.com>

The check to see if the uint32_t variable 'size' is less than zero
is redundant as it is unsigned and can never be less than zero.
Remove this redundant check.

Addresses-Coverity: ("Unsigned compared to zero")
