net: ipa: fix page free in ipa_endpoint_trans_release()

commit 155c0c90bca918de6e4327275dfc1d97fd604115 upstream.

Currently the (possibly compound) page 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_trans_release()
to use put_page() instead.
