tipc: Fix skb_under_panic when configuring TIPC without privileges
This patch prevents a TIPC configuration command requiring network administrator privileges from triggering an skbuff underrun if it is issued by a process lacking those privileges. The revised error handling code avoids the use of a potentially uninitialized global variable by transforming the unauthorized command into a new command, then following the standard command processing path to generate the required error message.
