If storage.conf graphdriver=="", devmapper shouldn't be tried

This patch removes devicemapper from the list of drivers tried when driver="" This change is necessary since tests in tools that use containers storage are being run when driver is not being specified. In this situation the test fails because devmapper returns and error other then ErrNotSupported. With this change a useful message will go to the logs if the user actually specifies "devicemapper" in config. Signed-off-by: Daniel J Walsh <[email protected]>
