mm: on remap assert that input range within the proposed VMA
Now we have range_in_vma_desc(), update remap_pfn_range_prepare() to check
whether the input range in contained within the specified VMA, so we can
fail at prepare time if an invalid range is specified.
This covers the I/O remap mmap actions also which ultimately call into
this function, and other mmap action types either already span the full
VMA or check this already.
