commit 70132763d5d2e94cd185e3aa92ac6a3ba89068fa upstream.
Currently the (possibly compound) pages used for receive buffers are
freed using __free_pages(). But according to this comment above the
definition of that function, that's wrong:
If you want to use the page's reference count to decide
when to free the allocation, you should allocate a compound
page, and use put_page() instead of __free_pages().
Convert the call to __free_pages() in ipa_endpoint_replenish_one()
to use put_page() instead.
Fixes: 6a606b90153b8 ("net: ipa: allocate transaction in replenish loop")
