[PATCH 1/2] driver/char: Drop run_in_exception_handler() ifdefary

[Andrew Cooper <andrew.cooper3@citrix.com>]

Since commit 60a9b0715055 ("xen: introduce CONFIG_GENERIC_BUG_FRAME"), the new
common bug.h provides an implementation of run_in_exception_handler() in all
cases, making the #else here dead.
