vfs: correct the comments of vfs_*() helpers

correct the comments of vfs_*() helpers in fs/namei.c, including:
1. vfs_create()
2. vfs_mknod()
3. vfs_mkdir()
4. vfs_rmdir()
5. vfs_symlink()

All of them come from the same commit:
6521f89170 "namei: prepare for idmapped mounts"

The @dentry is actually the dentry of child directory rather than
base directory(parent directory), and thus the @dir has to be
modified due to the change of @dentry.
