Rather than memcpy every packet that we receive from HID into our own local fixed-size array, we can just access the data directly through the original pointer. While we're at it, remove the few other places that assume a fixed maximum packet size and make them dynamic (in particular: temporary buffers created by the wacom_wac_queue_flush and wacom_intuos_bt_process_data functions; and the pen_fifo FIFO). To ensure pen_fifo allocation has access to the maximum used packet length, this commit also moves the function call to occur a little later in the probe process.

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.
