btrfs-progs: inspect: use btrfs_open_dir for btrfs inspect command
We can use btrfs_open_dir() to check whether target dir is
in btrfs's mount point before open, instead of checking it in
kernel space of ioctl, and return fuzzy error message.
Before patch:
# ./btrfs inspect-internal rootid /mnt/tmp1
ERROR: Failed to lookup root id - Inappropriate ioctl for device
btrfs inspect-internal rootid: rootid failed with ret=-1
# ./btrfs inspect-internal inode-resolve 256 /mnt/tmp1
ioctl ret=-1, error: Inappropriate ioctl for device
# ./btrfs inspect-internal min-dev-size /mnt/tmp1
Error invoking tree search ioctl: Inappropriate ioctl for device
After patch:
# ./btrfs inspect-internal rootid /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs inspect-internal inode-resolve 256 /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
# ./btrfs inspect-internal min-dev-size /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
