mempolicy: small header file cleanup 

Removes forward definition of vm_area_struct in linux/mempolicy.h.  We already
get it from the linux/slab.h -> linux/gfp.h include.

Removes the unused mpol_set_vma_default() macro from linux/mempolicy.h.

Removes the extern definition of default_policy since it is only referenced,
as it should be, in mm/mempolicy.c.
