    libxl: fix leaking logfile fds
    
    Per-domain log files were introduced in commit a30b08b7179. The FILE
    objects associated with these log files are stored in a hash table
    using domid as a key. When a domain is shutdown, destroyed, or
    otherwise powered-off, the FILE object is removed from the hash table,
    where the free function will close the FILE.
    
    Unfortunately the call to remove the FILE from the hash table occurs
    after setting domid=-1 in the libxlDomainCleanup() function. The
    object is never removed from the hash table, the free function is
    never called, and the underlying fd is leaked. Fix by removing the
    FILE object from the hash table before setting domid=-1.
