btrfs-progs: use btrfs_open_dir for btrfs device command
We can use btrfs_open_dir() to check whether the target dir is
under btrfs mount point before openning, instead of checking it in kernel
through ioctl, and returning a fuzzy error message.
Before patch:
# (/mnt/tmp is not btrfs mountpoint)
#
# btrfs device add -f /dev/sda13 /mnt/tmp
ERROR: error adding the device '/dev/sda13' - Inappropriate ioctl for device
#
After patch:
# btrfs device add -f /dev/sda13 /mnt/tmp
ERROR: not btrfs filesystem: /mnt/tmp
#
Similar fix for device remove and device usage.
