Fixes for 'blocking in fifoor state' problem of LTP tests. linux_*stat*() functions were opening files with O_RDONLY to get major/minor pair for char/block special files. Unfortunately, when these functions are used against fifo, it is blocked forever because there is no writer. Instead, we only open char/block special files for major/minor conversion. We have to get rid of kern_open() entirely from translate_path_major_minor() but today is not the day. While I am here, add checks for errors before calling translate_path_major_minor().
