[PATCH] fs/d_path.c: Supply missing internal.h include file

[Pujin Shi <shipujin.t@xxxxxxxxx>]

If the header file containing a function's prototype isn't included by
the sourcefile containing the associated function, the build system
complains of missing prototypes.

Fixes the following W=1 kernel build warning(s):

fs/d_path.c:311:7: warning: no previous prototype for ‘simple_dname’ [-Wmissing-prototypes]
