Subject: mm: pagewalk: fix unused variable warning
One of the pagewalk patches introduced a harmless warning:
mm/hmm.c: In function 'hmm_vma_walk_pud':
mm/hmm.c:478:9: error: unused variable 'pmdp' [-Werror=3Dunused-variable]
pmd_t *pmdp;
^~~~
mm/hmm.c:477:30: error: unused variable 'next' [-Werror=3Dunused-variable=
]
unsigned long addr =3D start, next;
^~~~
Remove both of the now-unused variables.
