sysfs: remove signedness from sysfs_get_dirent

sysfs_get_dirent is usually invoked with a string literal, which
have the type char[].  While the toplevel Makefile
disables -Wpointer-sign, other Makefiles like

arch/x86/boot/compressed/Makefile

redefine KBUILD_CFLAGS. Fixes the warning:

        return kernfs_find_and_get(parent, name);
