cifs: Fix reading into an ITER_FOLIOQ from the smbdirect code
When performing a file read from RDMA, smbd_recv() prints an "Invalid msg
type 4" error and fails the I/O. This is due to the switch-statement there
not handling the ITER_FOLIOQ handed down from netfslib.
Fix this by collapsing smbd_recv_buf() and smbd_recv_page() into
smbd_recv() and just using copy_to_iter() instead of memcpy(). This
future-proofs the function too, in case more ITER_* types are added.
Fixes: ee4cdf7ba857 ("netfs: Speed up buffered reading")
