[PATCH] inotify: check for NULL inode in inotify_d_instantiate

The spufs file system creates files in a directory before instantiating the
directory itself, which causes a NULL pointer access in
inotify_d_instantiate since c32ccd87bfd1414b0aabfcd8dbc7539ad23bcbaa.

I'd like to keep this behavior since it means that the user will not have
access to files in the directory before I know that I succeed in creating
everything in it.  This patch adds a simple check for the inode to keep
that working.
