gfs2_convert: mask out proper bits when identifying symlinks
This patch masks out the proper file type bit in order to distinguish files from symlinks. Include stat.h defines: So the check for "di_mode & S_IFLNK" will match regular files, not just symlinks. The problem was that gfs2_convert was matching regular files and treating them as symlinks, which destroyed the di_blocks field in the dinode. The patch also has some minor cleanups.
