Fix build with CONFIG_BLOCK off.
Building git-2d94dfc with CONFIG_BLOCK turned off gives me:
drivers/base/core.c: In function 'device_add_class_symlinks':
drivers/base/core.c:704: error: 'part_type' undeclared (first use in this
function)
drivers/base/core.c:704: error: (Each undeclared identifier is reported only
once
drivers/base/core.c:704: error: for each function it appears in.)
drivers/base/core.c: In function 'device_remove_class_symlinks':
drivers/base/core.c:743: error: 'part_type' undeclared (first use in this
function)
git-blame points to Kay Sievers.
The problem is obvious. I think te solution is too ;).
Tested with a silly configuration that contains just enough wits to boot
and get to the prompt of klibc-dash on the built-in initramfs using:
qemu -m 8 -cpu pentium -serial stdio -cdrom arch/x86/boot/image.iso
Compile-tested i386-defconfig.

Oh, and the compile-problem still exists in git-99f1c97. The git-tree is
changing faster than I can test the patch and write an e-mail :-/.
