If we didn't find what we are looking for in /proc/partitions,
we're not going to find it by scanning every node under /dev, either.
But that's just what btrfs_scan_for_fsid() does.
Remove that fallback; at that point btrfs_scan_for_fsid() just calls
scan_for_btrfs(), so remove the wrapper & call it directly.
Side note: so, these paths always use /proc/partitions, not libblkid.
Userspace-intiated scans default to libblkid. I presume this is
part of the design, and intentional? Anyway, not changing it now!
