Log Message:
In XEN PV, the idt vector table is not required to be altered at
runtime, since only entries for exceptions/traps are registered with
the hypervisor and interrupts are managed via a completely different
mechanism.

This change uses the idt_vec_reserve() mechanism nevertheless,
modifying it slightly to only do namespace management in XEN, while on
native it will continue to do idt entry init as before.

Rationale: Consistent API usage and potential future merging of
XEN/non-XEN code.

There are no functional changes in this commit.
