Since commit 63ed8de4be ("mld: add mc_lock for protecting per-interface
mld data"), the newly allocated struct ifmcaddr6 cannot be removed until
inet6_dev->mc_lock is released, so mca_get() and mc_put() are unnecessary.
Let's remove the extra refcounting.
Note that mca_get() was only used in __ipv6_dev_mc_inc().

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 reStructuredText markup notation.
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.
