Refactor ice_fetch_rx_buf and ice_add_rx_frag in a way that we have standalone functions that do either the skb construction or frag addition to previously constructed skb. The skb handling between rx_bufs is spread among various functions. The ice_get_rx_buf will retrieve the skb pointer from rx_buf and if it is a NULL pointer then we do the ice_construct_skb, otherwise we add a frag to the current skb via ice_add_rx_frag. Then, on the ice_put_rx_buf the skb pointer that belongs to rx_buf will be cleared. Moving further, if the current frame is not EOP frame we assign the current skb to the rx_buf that is pointed by updated next_to_clean indicator. What is more during the buffer reuse let's assign each member of ice_rx_buf individually so we avoid the unnecessary copy of skb. Last but not least, this logic split will allow us for better code reuse when adding a support for build_skb.

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.
