Daniel Tang 85580cbac5 ACPI: TAD: Add missing sysfs_remove_group() for ACPI_TAD_RT
commit 4aac453dec upstream.

Previously, after `rmmod acpi_tad`, `modprobe acpi_tad` would fail
with this dmesg:

sysfs: cannot create duplicate filename '/devices/platform/ACPI000E:00/time'
Call Trace:

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.
