fix: wait on userfence when VM immediate is used

Browse Source 
Removed if condition when calling vm_bind in order to
reflect changed in KMD.
Specifically, dii-4347 to dii-4349 include changes on
strict fence ordering on vm_bind, where user fence has
to be inserted regardless of using pagefault or explicit
residency.
