selftests/bpf: Fix total_bytes in msg_loop_rx in test_sockmap

Browse source

[ Upstream commit 523dffccba ]

total_bytes in msg_loop_rx should also take push into account, otherwise
total_bytes will be a smaller value, which makes the msg_loop_rx end early.

Besides, total_bytes has already taken pop into account, so we don't need
to subtract some bytes from iov_buf in sendmsg_test. The additional
subtraction may make total_bytes a negative number, and msg_loop_rx will
just end without checking anything.

Fixes: 18d4e900a4 ("bpf: Selftests, improve test_sockmap total bytes counter")
Fixes: d69672147f ("selftests, bpf: Add one test for sockmap with strparser")
