LE Create Connection Complete - crash on Command Disallowed 

When LE Create Connection Complete is received with status "Command
Disallowed", we can't tell which state we should transition to. This
can be triggered only in case of rare race condition. Crash to recover.

This was introduced in 3c7bb20d, when
generic handling of all errors to this event was added.
