Zide Chen e48962faa6 hv: optimize run_vcpu() for nested ...

This patch implements a separate path for L2 VMEntry in run_vcpu(),
which has several benefits:

- keep run_vcpu() clean, to reduce the number of is_vcpu_in_l2_guest()
  statements:
  - current code has three is_vcpu_in_l2_guest() already.
  - supposed to have another 2 statement so that nested VMEntry won't
    hit the "Starting vCPU" and "vCPU launched" pr_info() and a few
    other statements in the VM launch path.

- save few other things in run_vcpu() that are not needed for nested.
