SLOs created after commit 2d25fe6ad3573b2a06b6b3e5e66493d7b0c55693 have an explicit X-Object-Sysmeta-SLO-Size attribute. Fetching one of those with a range like "bytes=100-" would crash and cause a 500. This commit fixes the crash. Closes-Bug: #1656147 Change-Id: I174ed98b4f01a5943af12177d6f8c3586f049778
