Parav Pandit c4c8aff5a9 IB/core: Do not notify GID change event of an unregistered device
When IB device is undergoing unregistration, the GID cache is always
cleaned up after all clients are unregistered with the below flow.

__ib_unregister_device()
  disable_device()
  ib_cache_cleanup_one()
    gid_table_cleanup_one()
      cleanup_gid_table_port()

There is no use in generating a GID change event at this stage, where
there is no active client of the device and device is nearly unregistered.

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.

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.
