io_uring/zcrx: improve area validation
[ Upstream commit d760d3f59f0d8d0df2895db30d36cf23106d6b05 ]
dmabuf backed area will be taking an offset instead of addresses, and
io_buffer_validate() is not flexible enough to facilitate it. It also
takes an iovec, which may truncate the u64 length zcrx takes. Add a new
helper function for validation.
