[CRYPTO] padlock: Rearrange context structure to reduce code size

i386 assembly has more compact instructions for accessing 7-bit offsets.
So by moving the large members to the end of the structure we can save
quite a bit of code size.  This patch shaves about 10% or 300 bytes off
the padlock-aes file.
