net: devmem: remove net_iov_area base_virtual
Since commit 083e64a3af77 ("net: devmem: replace gen_pool with
freelist"), a binding has a single net_iov_area covering the whole
dma-buf, and base_virtual is always 0. Its only reader is
net_iov_virtual_addr(), where it adds nothing. io_uring zcrx never
uses it.
Drop the field and the store, and compute the dma-buf offset from the
net_iov index alone.
No functional change. From review feedback on:
