Revert "livepatch: Remove reliable stacktrace check in klp_try_switch_task()"



This reverts commit 1d98a69e. Commit
31adf230 ("livepatch: Convert error about unsupported reliable
stacktrace into a warning") weakened the enforcement for architectures
to have reliable stack traces support. The system only warns now about
it.

It only makes sense to reintroduce the compile time checking in
klp_try_switch_task() again and bail out early.
