Clean up AES context alignment code

Use a single auxiliary function to determine rk_offset, covering both
setkey_enc and setkey_dec, covering both AESNI and PADLOCK. For AESNI, only
build this when using the intrinsics-based implementation, since the
assembly implementation supports unaligned access.

Simplify "do we need to realign?" to "is the desired offset now equal to
the current offset?".
