ethtool: fix ethnl_bitmap32_not_zero() bit interval semantics
ethnl_bitmap32_not_zero() should return true if some bit in [start, end)
is set:
- Fix inverted memchr_inv() sense: return true when the scan finds a
non-zero byte, not when the middle words are all zero.
- Return false for an empty interval (end <= start).
- When end is 32-bit aligned, indices in [start, end) do not include any
bits from map[end_word]; return false after earlier checks found no
non-zero data.
Fixes: 10b518d4e6dd ("ethtool: netlink bitset handling")
