eth: Rename and properly align br_reserved_address array
Since this array is no longer part of the bridge driver, it should
have an 'eth' prefix not 'br'.
We also assume that either it's 16-bit-aligned or the architecture has
efficient unaligned access. Ensure the first of these is true by
explicitly aligning it.
