[PATCH net v2 2/2] net: ipa: fix page free in ipa_endpoint_replenish_one()

[Alex Elder]

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")
