Description

There is a bug at the end of server_put_mount() calling server_deregister_mount() even if this isn't the last reference.

Fixing this would probably remove the need for server_

{get,put}

_mount_2(). These functions could be removed and the one caller of server_get_mount_2() could be changed to call server_get_mount() and server_put_mount() at the end.
