Fix an improperly ignored error in SQLite

This looks like a case of boilerplate error handling making it
too easy to miss a legitimately ignored error, which is annoying.
In a more featureful language most of the SQL code here could be
macros (at the very least, Rust would have forced us to handle
all error cases, not just the one seen here).

Found while looking through the Libpod DB code, no actual bug I
can think of associated with this.
