net: context: Add status to connect callback

Browse source 
It is useful that the user API can know whether the connection
was established properly or not. So this commit adds status
parameter to connect callback in net_context API.

The call to connect callback needs to be set properly in TCP
code. This commit does not fix the connect callback call which
is not properly done right now in net_context.c.
