* Reserving areas never put down their reference of their address space when

removed in several cases.
* vfs_get_vnode_cache() now always gives out a reference to the cache it
  returns; if it needs to allocate a new one, the vnode owns one reference,
  and the caller another.
* therefore, file_cache_create() now owns a reference to its vm_cache_ref, and
  frees it in file_cache_delete().
