rdma_translate_ip() is done while resolving address for the loopback
addresses. The current flow is convoluted with resolve neighbor being
optional.
This patch simplifies the code in following ways.
(a) Use common code between IPv4 and IPv6 for address translation,
loopback checks and acquiring netdevice.
(b) During neigh resolve in addr_resolve_neigh(), only copy destination
address.
(c) Always resolve the source address before the destination address,
because it doesn't depend on resolving neigh being requested or not.
This helps to reduce 3 calls of rdma_copy_addr and rdma_translate_ip to
one and makes it easier to follow the code flow.
Now that ib_nl_fetch_ha() doesn't depend on dst, drop dst argument from
ib_nl_fetch_ha().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
