    kern: Fix memory leak in kdmsg_iocom_uninit()
    
    When kdmsg_iocom_uninit() is called but no connection was ever
    established (no reader/writer threads), a PING message was allocated and
    queued but never freed. This caused a 120-byte leak from the HAMMER2-msg
    allocator on shutdown.
    
    Fix this by calling kdmsg_drain_msgq() to clean up any queued messages.
    
    This fixes the 'malloc_uninit: 120 bytes of HAMMER2-msg still allocated'
    warning.  Note that this warning already disappeared after fixing the
    hammer2_ioctl_recluster() bug in commit
    c5cc81fefa166cc45657541c155797f0cff88c62.
