Jon Maloy e0e853ac03 tipc: fix access of released memory 
When the function tipc_group_filter_msg() finds that a member event
indicates that the member is leaving the group, it first deletes the
member instance, and then purges the message queue being handled
by the call. But the message queue is an aggregated field in the
just deleted item, leading the purge call to access freed memory.

We fix this by swapping the order of the two actions.
