arm64: asm-extable: move data fields

In subsequent patches we'll need to fill in extable data fields in
regular assembly files. In preparation for this, move the definitions of
the extable data fields earlier in asm-extable.h so that they are
defined for both assembly and C files.

There should be no functional change as a result of this patch.
