nilfs2: fix incorrect masking of permission flags for symlinks
commit 5924e6ec1585445f251ea92713eb15beb732622a upstream.
The permission flags of newly created symlinks are wrongly dropped on
nilfs2 with the current umask value even though symlinks should have 777
(rwxrwxrwx) permissions:
$ umask
0022
$ touch file && ln -s file symlink; ls -l file symlink
-rw-r--r--. 1 root root 0 Jun 23 16:29 file
lrwxr-xr-x. 1 root root 4 Jun 23 16:29 symlink -> file
This fixes the bug by inserting a missing check that excludes
symlinks.
