Subject: [PATCH 06/33] x86/asm/xen: Set ELF function type for xen_adjust_exception_frame()

xen_adjust_exception_frame() is a callable function, but is missing the
ELF function type, which confuses tools like stacktool.

Properly annotate it to be a callable function.  The generated code is
unchanged.
