hv: bugfix for debug commands with smp_call

Browse Source 
With cpu-sharing enabled, there are more than 1 vcpu on 1 pcpu, so the
smp_call handler should switch the vmcs to the target vcpu's vmcs. Then
get the info.

dump_vcpu_reg and dump_guest_mem should run on certain vmcs, otherwise,
there will be #GP error.

Renaming:
vcpu_dumpreg -> dump_vcpu_reg
switch_vmcs -> load_vmcs
