NVMe: Correct sg list setup in nvme_map_user_pages
Our SG list was constructed to always fill the entire first page, even
if that was more than the length of the I/O. This is probably harmless,
but some IOMMUs might do something bad.
Correcting the first call to sg_set_page() made it look a lot closer to
the sg_set_page() in the loop, so fold the first call to sg_set_page()
into the loop.
