dump vcpu registers on correct vcpu

Browse Source 
after updated cpu context get/set method, the vcpu_dumreg cmd is not
correct anymore as the registers may read from VMCS but meantime hv
shell may not be running on target vcpu.

this patch take use of smp_call_function for vcpu dumpreg and make the
dump always come from correct vcpu.

v2:
- use str pointer to get vcpu_dumpreg context instead of print out directly
  in notify handler.
