8e97974216
Fixed return rc after:
...
routeQuery()
(dcb->func).close(dcb);
This will prevent setting again dcb->sate = DCB_STATE_POLLING in return_rc label.
The log entry for
[gw_read_client_event] ioctl FIONREAD for fd 21 failed. errno 9, Bad file descriptor. dcb->state = 3
now is not present anymore.

dcb_close sets some session fields to NULL:
...
dcb->session->client = NULL;
dcb->session = NULL;
There is a local copy of dcb->seesion before setting it to NULL

Holding error log's block buffer registration until all logs were written caused deadlock if block buffers were full. Now buffer registrations don't overlap.

gw_do_connect_to_backend returned zero in case where connect failed with errno EINPROGRESS. Should have returned 1 to indicate that connection will be established asynchronously.
...
In the same case, checking for error by using getsockopt should be done when select returns, not after connect (man 2 connect).
