posixshm: Fix a double unlock in shm_partial_page_invalidate()HEADmain

For some reason, shm_partial_page_invalidate() unlocks the object upon
an error, but its callers don't expect this.  Don't do any special error
handling.  Keep the subroutine anyway since the name is a bit clearer
than vm_page_grab_zero_partial().

While here, normalize the object pointer used for locking in
shm_deallocate().
