shmem: fix obsolete comment in shmem_getpage_gfp()

Replace "fault_mm" with "vmf" in code comment because commit cfda05267f7b
("userfaultfd: shmem: add userfaultfd hook for shared memory faults") has
changed the prototpye of shmem_getpage_gfp() - pass vmf instead of
fault_mm to the function.

Before:
static int shmem_getpage_gfp(struct inode *inode, pgoff_t index,
		struct page **pagep, enum sgp_type sgp,
		gfp_t gfp, struct mm_struct *fault_mm, int *fault_type);
After:
static int shmem_getpage_gfp(struct inode *inode, pgoff_t index,
		struct page **pagep, enum sgp_type sgp,
		gfp_t gfp, struct vm_area_struct *vma,
		struct vm_fault *vmf, vm_fault_t *fault_type);
