ice: xsk: fix GCC version checking against pragma unroll presence
Pragma unroll was introduced around GCC 8, whereas current xsk code in
ice that prepares loop_unrolled_for macro that is based on mentioned
pragma, compares GCC version against 4, which is wrong and Stephen
found this out by compiling kernel with GCC 5.4 [0].
Fix this mistake and check if GCC version is >= 8.
