xen/arm: Disable interrupts for the entire duration of the context switch

Not just while saving state. Otherwise there is a race between interrupts
arriving and updating the LR state and gic_restore_state overwriting them with
the saved state.

With this change we no longer need to disable interrupts in gic_restore_state.
