For the new regular tmpfs vnode, v_object is initialized before
insmntque() is called. The standard insmntque destructor resets the
vop vector to deadfs one, and calls vgone() on the vnode. As result,
v_object is kept unchanged, which triggers an assertion in the reclaim
code, on instmntque() failure. Also, in this case, OBJ_TMPFS flag on
the backed vm object is not cleared.
Provide the tmpfs insmntque() destructor which properly clears
OBJ_TMPFS flag and resets v_object.
