btrfs: replace ASSERT with proper error handling in stripe lookup fallback

Browse source

After falling back to the previous item in btrfs_delete_raid_extent(),
the code uses ASSERT(found_start <= start) to verify the found extent
actually precedes our target range. If the B-tree state is unexpected
(e.g. no overlapping extent exists), this triggers a kernel BUG/panic
in debug builds, or silently continues with wrong data otherwise.

Replace the ASSERT with a proper bounds check that returns -ENOENT if
the found extent does not actually overlap with the start position.
