Toke Høiland-Jørgensen 425d239379 bpf: Fix release of page_pool in BPF_PROG_RUN in test runner ... The live packet mode in BPF_PROG_RUN allocates a page_pool instance for each test run instance and uses it for the packet data. On setup it creates the page_pool, and calls xdp_reg_mem_model() to allow pages to be returned properly from the XDP data path. However, xdp_reg_mem_model() also raises the reference count of the page_pool itself, so the single page_pool_destroy() count on teardown was not enough to actually release the pool. To fix this, add an additional xdp_unreg_mem_model() call on teardown.
