Subject: [PATCH v2 09/14] btrfs: selftests: check for correct return value
 of failed lookup

From: Johannes Thumshirn <johannes.thumshirn@....com>

Commit 5e72aabc1fff ("btrfs: return ENODATA in case RST lookup fails")
changed btrfs_get_raid_extent_offset()'s return value to ENODATA in case
the RAID stripe-tree lookup failed.

Adjust the test cases which check for absence of a given range to check
for ENODATA as return value in this case.
