[PATCH] fetch2: reraise IOError during download

Fixes [YOCTO #16268]

Adds a missing "raise" statement to download that ensures when there is an IOError/OSError that is is correctly reported and not silently discarded.
When an IOError is thrown in this case do_fetch silently passes which then leads to downstream failures in do_unpack when the file doesn't exist.
