While ntfs3 supports discards, FITRIM ioctl() command has defined only for regular files. This may confuse users trying to invoke `fstrim` utility with the directory argument (for example, call `fstrim <mountpoint>` which is the common practice). In this case, ioctl() returns -ENOTTY without any error messages in kernel ring buffer, this may be easily interpreted as no support for discards in ntfs3 driver. Currently only FITRIM command implemented in ntfs_ioctl() and passed inode used only for dereferencing NTFS superblock, so no need for separate ioctl() handler for directories, just add existing ntfs_ioctl() handler to ntfs_dir_operations.
