[PATCH -mmotm/-next] fs: fs_parser: fix printk format warning

[Randy Dunlap]

From: Randy Dunlap <rdunlap@infradead.org>

Fix printk format warning (seen on i386 builds) by using ptrdiff
format specifier (%t):

../fs/fs_parser.c:413:6: warning: format ‘%lu’ expects argument of type ‘long unsigned int’, but argument 3 has type ‘int’ [-Wformat=]

Now seen in upstream on all 32-bit platforms, I guess.
