remove unnecessary logs (#1599)

Logging ErrInvalidConn when the connection already closed doesn't
provide any help to users.

Additonally, database/sql now uses Validator() to check connection
liveness before calling query methods.
So stop using `mc.log(ErrInvalidConn)` idiom.

This PR includes some cleanup and documentation relating to
`mc.markBadConn()`.
