The f_op->mmap interface is deprecated, so update the vmbus driver to use its successor, mmap_prepare. This updates all callbacks which referenced the function pointer hv_mmap_ring_buffer to instead reference hv_mmap_prepare_ring_buffer, utilising the newly introduced compat_set_desc_from_vma() and __compat_vma_mmap() to be able to implement this change. The UIO HV generic driver is the only user of hv_create_ring_sysfs(), which is the only function which references vmbus_channel->mmap_prepare_ring_buffer which, in turn, is the only external interface to hv_mmap_prepare_ring_buffer. This patch therefore updates this caller to use mmap_prepare instead, which also previously used vm_iomap_memory(), so this change replaces it with its mmap_prepare equivalent, mmap_action_simple_ioremap().
