[ Upstream commitb3e2080694] Commit773225388d("net: thunderx: Optimize page recycling for XDP") added code to nicvf_alloc_page() that inadvertently disables receive buffer page recycling for the non-XDP case by always NULL'ng the page pointer. This patch corrects two if-conditionals to allow for the recycling of non-XDP mode pages by only setting the page pointer to NULL when the page is not ready for recycling.

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.
