odb: shut up gcc warnings regarding uninitilized variables
The `error` variable is used as a return value in the out-section of
both `odb_read_1` and `read_prefix_1`. While the value will actually
always be initialized inside of this section, GCC fails to realize this
due to interactions with the `found` variable: if `found` is set, the
error will always be initialized. If it is not, we return early without
reaching the out-statements.
Shut up the warnings by initializing the error variable, even though it
is unnecessary.
