    sys/vfs/hammer2: Fix memory leak for second PFS mount and after
    
    When mounting, hmp and its ->devvpl are initialized only if it's
    the first PFS mount of that hmp. For the second PFS mount and after,
    malloc'd memory in a devvpl list (64 bytes per device per PFS)
    has been leaked.
    
    Found on FreeBSD on kldunload.
    --
    Warning: memory type hammer2_mount leaked memory on destroy (1 allocations, 64 bytes leaked).
