Btrfs-progs: bugfix for scrubbing single devices
Scrub can be invoked to scrub only a single device of a (mounted) filesystem.
The code determines whether the given path is a mountpoint of a filesystem
by issueing a btrfs-specific ioctl to it. Only in case of EINVAL it assumed
it may be a device, all other errnos just caused it fail, but some devices
(correctly) return ENOTTY. This patch adds this to the error check.
