[bitbake][wrynose][2.18][PATCH v2 1/8] fetch2: reraise IOError during download

From: Anthony Squires <[email protected]>

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.
