net/handshake: Squelch allocation warning during Kunit test

chucklever · kuba-moo · commit b21c7ba6d9a5 · 2023-05-22T19:24:52.000-07:00
The "handshake_req_alloc excessive privsize" kunit test is intended to check what happens when the maximum privsize is exceeded. The WARN_ON_ONCE_GFP at mm/page_alloc.c:4744 can be disabled safely for this test.
