vfio/iova_bitmap: Explicitly include linux/slab.h

kzalloc/kzfree are used so include `slab.h`. While it happens to work
without it, due to commit 8b9f3ac5b01d ("fs: introduce alloc_inode_sb() to
allocate filesystems specific inode") which indirectly includes via:

. ./include/linux/mm.h
.. ./include/linux/huge_mm.h
... ./include/linux/fs.h
.... ./include/linux/slab.h

Make it explicit should any of its indirect dependencies be dropped/changed
for entirely different reasons as it was the cause prior to commit above
recently (i.e. <= v5.18).
