staging: comedi: ni_670x: fix compile on ARCH=arm
The kbuild test robot reported a build error on ARCH=arm about
implicit declaration of the functions 'kmalloc' and 'kfree'.
On ARCH=x86 the slab.h header is indirectly included by pci.h,
this does not occur on ARCH=arm.
Include slab.h directly instead of relying on some other header
to include it.
