linux-user: Check copy_from_user() return value in vma_dump_size()
Coverity points out that we don't check the return value from
copy_from_user() in vma_dump_size(). This is to some extent
a "can't happen" error since we've already checked the page
with an access_ok() call earlier, but it's simple enough to
handle the error anyway.
Fixes: Coverity CID 1432362
