ice: use generic unrolled_count() macro
ice, same as i40e, has a custom loop unrolling macros for unrolling
Tx descriptors filling on XSk xmit.
Replace ice defs with generic unrolled_count(), which is also more
convenient as it allows passing defines as its argument, not hardcoded
values, while the loop declaration will still be usual for-loop.
