drivers: do not consider overlay cleanup error fatal 

For some reason that we have not yet determined, the overlay that we use
for the drivers code sometimes fails to unmount with EBUSY.

When it happens, the _list_drivers task would fail, making subsequent
GET calls to /drivers?wait=true fail as well and produce an error
report.

We now mark failures in the overlay unmount operation as non fatal.
