Konstantin Belousov 7560005c41 After the object lock was dropped, the object' reference count could ...

change.  Retest the ref_count and return from the function to not
execute the further code which assumes that ref_count == 1 if it is
not.  Also, do not leak vnode lock if other thread cleared OBJ_TMPFS
flag meantime.
