net: libwx: handle page_pool_dev_alloc_pages error
page_pool_dev_alloc_pages could return NULL. There was a WARN_ON(!page)
but it would still proceed to use the NULL pointer and then crash.
This is similar to commit 001ba0902046
("net: fec: handle page_pool_dev_alloc_pages error").
This is found by our static analysis tool KNighter.
