[PATCH RFC net-next v1] net: Add maintainer entry for netmem & friends

[Mina Almasry <almasrymina@google.com>]

There is some needless friction with regards to whether netmem_ref,
net_iov, and memory provider patches being CC'd to netdev or not. Add
clear policy and put it in the MAINTAINERS file so get_maintainer.pl
does the right thing by default.

All changes to current and future memory providers should be CC'd to
netdev. The devmem memory provider happens to be under net so is
covered by 'NETWORKING [GENERAL]' as-is. The io_uring memory provider
happens to be outside of net/ though, so add an explicit file entry
for that.

Note that the memory provider changes need _not_ be merged through net
or net-next, but the changes should be CC'd to netdev. Target the
appropriate tree using the [PATCH ...] prefix.

All changes using or modifying netmem_ref or struct net_iov should also
be sent to netdev, so add a content regex for that. Patches modifying
the netmem_ref or net_iov infra should also target net or net-next
([PATCH net] or [PATCH net-next]). This is already the convention.

Note that no maintainers or reviewers are dedicated to this entry.
We don't presume to overburden existing maintainers or add new ones; let
the maintainers nominate folks whenever they feel appropriate. But make
sure changes are sent to the correct lists.

Tested by creating a couple of trivial changes in io_uring/zcrx.[h|c]
and adding netmem_ref and net_iov in other subsystems, and looking at
the get_maintainer.pl results.
