selftests/bpf: Fix SENDPAGE data logic in test_sockmap

Browse source

[ Upstream commit 4095031463 ]

In the SENDPAGE test, "opt->iov_length * cnt" size of data will be sent
cnt times by sendfile.
1. In push/pop tests, they will be invoked cnt times, for the simplicity of
msg_verify_data, change chunk_sz to iov_length
2. Change iov_length in test_send_large from 1024 to 8192. We have pop test
where txmsg_start_pop is 4096. 4096 > 1024, an error will be returned.
