xfs: fix xfs_quota remove error

The xfs_quota returns ENOSYS when remove command is executed.
Reproducable with following steps.

    # mount -t xfs -o uquota /dev/sda7 /mnt/mp1
    # xfs_quota -x -c off -c remove
    XFS_QUOTARM: Function not implemented.

The remove command is allowed during quotaoff, but xfs_fs_set_xstate()
checks whether quota is running, and it leads to ENOSYS.

To solve this problem, add a check for X_QUOTARM.
