[PATCH] sd: assign appropriate log level

[David Singleton]

From: Shikhar Dogra <shidogra@xxxxxxxxx>

Reduce chatter on console for usb hotplug.
KERN_ERR is too high severity for these messages, moving them
to KERN_WARNING

USB devices never have a Caching Mode page, it doesn't make
sense to make it an error when you have tons of USB devices where
the print is useless, and not an error.

For second message, the condition is not an error. The existing
workaround of assuming a write through cache doesn't limit
functionality in any way.
