the vma range size is always page size aligned in mmap, while the real io space range may not be page aligned, thus leading to range check failure in the uio_mmap_physical(). for example, in a case of io range size "mem->size == 1KB", and we have (vma->vm_end - vma->vm_start) == 4KB, due to "len" is aligned to page size in do_mmap_pgoff(). now fix this issue by align mem->size to page size in the check.
