SVN rev 219604 on 2011-03-13 12:56:46Z by bschmidt
When injecting frames a temporary node is faked, during this several
uses of ic_curchan occur. Due to the nature of a scan, switching
channels constantly and all this happening without any kind of locks
held, it might happen that ic_curchan points to nowhere leading to
panics. Fix this by not allowing frame injections while in SCAN state.
