ntfs: return DT_UNKNOWN on inode lookup failure in readdir

Browse source

ntfs_reparse_tag_dt_types() returns PTR_ERR(vi) when ntfs_iget()
fails, but its return type is unsigned int and the caller passes
the value straight to dir_emit() as d_type. A stale or corrupt MFT
reference in a directory index thus makes readdir report a garbage
d_type value to userspace.

Return DT_UNKNOWN on lookup failure instead.
