arm64: armv8_deprecated: move aarch32 helper earlier

commit 0c5f416219da3795dc8b33e5bb7865a6b3c4e55c upstream.

Subsequent patches will rework the logic in armv8_deprecated.c.

In preparation for subsequent changes, this patch moves some shared logic
earlier in the file. This will make subsequent diffs simpler and easier to
read.

At the same time, drop the `__kprobes` annotation from
aarch32_check_condition(), as this is only used for traps from compat
userspace, and has no risk of recursion within kprobes. As this is the
last kprobes annotation in armve8_deprecated.c, we no longer need to
include <asm/kprobes.h>.
