mm/migrate_device: fix function name in kernel-doc

Browse Source 
The kernel-doc for migrate_device_range() says that migrate_vma_setup() is
similar to itself.  Refer to migrate_device_range() as the subject of the
comparison, making the distinction between virtual-address-based and
device-PFN-based migration clear.
