btrfs-progs: don't fall back to recursive /dev scan
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!
