    ipc_kmsg: assert non-NULL kmsg in ipc_kmsg_free
    
    ipc_kmsg_free() dereferenced kmsg->ikm_size without any check that
    kmsg was non-NULL. Any caller passing IKM_NULL would crash on that
    dereference.
    
    Rather than silently returning on a NULL kmsg -- which would hide a
    real bug in the caller -- follow the convention already used
    throughout this file (see ipc_kmsg_rmqueue, ipc_kmsg_copyout_dest,
    etc.) and assert() the precondition, so a misbehaving caller is
    caught loudly in debug/MACH_ASSERT builds instead of being papered
    over.
    
    No other behavioral changes.
