hv: fix the vm pointer check before use

Browse Source 
After using get_vm_from_vmid(), vm pointer is always not NULL. But there are still many NULL pointer checks.
This commit replaced the NULL vm pointer check with a validation check which checks the vm status.
In addition, NULL check for pointer returned by get_sos_vm() and get_vm_config() is removed.
