[release-branch.go1.8] database/sql: ensure driverConns are closed if not returned to pool
Previously if a connection was requested but timed out during the
request and when acquiring the db.Lock the connection request
is fulfilled and the request is unable to be returned to the
connection pool, then then driver connection would not be closed.
No tests were added or modified because I was unable to determine
how to trigger this situation without something invasive.
