From 7abdf3e5c36197c5518edf53acb98611559dadec Mon Sep 17 00:00:00 2001
From: Richard Purdie <rpurdie@linux.intel.com>

Subject: bitbake/fetch: Checksum validity fixes
If the checksum check failed, the .md5 stamp file would still have been created
meaning subsequent builds would proceed with the corrupt file. Reorder the calls
to avoid this. Also raise a specific error for the checksum not specified error
case.
