cifs: skip alloc when request has no pages
When smb3_init_transform_rq() was being called with requests (@old_rq)
which had no pages, it was unnecessarily allocating a single page for
every request in @new_rq.
Fix this by skipping page array allocation when requests have no pages
(e.g. !smb_rqst::rq_npages).
Also get rid of deprecated kmap() and use kmap_local_page() instead
while we're at it.
