metrics: tidy: move local assign inside loop

The bootdata assignments were outside the 'valid file' check loop,
which meant in the case there was a data directory which did not
contain a valid scaling file, we would fail the assignment (as the
`local_bootdata` would be empty).

Fix by moving the assignments into the loop, thus only assigning when
we know we have valid data.
