staging: nvec: Capitalize outputs to match the rest of the driver

Noticing that some messages were capitalized and some weren't, I
capitalized them to match the rest. This makes the messages relatively
easier to understand for an end user, and reduces confusion about
capitalization. A comment was also capitalized.
