Chenguang Zhao 6d4bf7bedd ethtool: fix ethnl_bitmap32_not_zero() bit interval semantics ...

[ Upstream commit 3d042592eb ]

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.
