Konstantin Belousov c4be9169c0 Do not leak rv->psind in some specific situations.
Suppose that we have an object with a mapped superpage, and that all
pages in the superpages are held (by some driver).  Additionally,
suppose that the object is terminated, e.g. because the only process
mapping it is exiting.  Then the reservation is broken, but the pages
cannot be freed until later, when they are unheld.  In this situation,
the reservation code cannot clean psind, since no pages are freed, and
the page is freed and then reused with invalid psind.

Clean psind on vm_reserv_break() to avoid the situation.
