The format of the arm64 and x86 exception table entries is essentially
the same as of commits:
46d28947d9876fc0 ("x86/extable: Rework the exception table mechanics")
d6e2cc5647753825 ("arm64: extable: add `type` and `data` fields")
Both use a 12-byte entry consisting of two 32-bit relative offsets and
32 bits of (absolute) data, and their sort functions are identical aside
from commentary, with arm64 saying:
/* Don't touch the fixup type or data */
... and x86 saying:
/* Don't touch the fixup type */
Unify the two behind a common sort_relative_table_with_data() function,
retaining the arm64 commentary.
There should be no functional change as a result of this patch.
