MXS-1804: Fix hanging of large session commands

Browse Source 
Large session commands weren't properly handled which caused the router to
think that the trailing end of a multi-packet query was actually a new
query.

This cannot be confidently solved in 2.2 which is why the router session
is now closed the moment a large session command is noticed.
