btrfs-progs: fragments: use btrfs_open_dir for btrfs-fragments 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
deeper code, and return fuzzy error message.
Before patch:
./btrfs-fragments -o 123 /mnt/tmp1
ERROR: can't perform the search
After patch:
# ./btrfs-fragments -o 123 /mnt/tmp1
ERROR: not a btrfs filesystem: /mnt/tmp1
