[igt-dev] [PATCH i-g-t] tests/sw_sync: Accept bytes transferred between sendmsg/recvmsg

[Chris Wilson]

sendmsg/recvmsg return the number of bytes transferred, not just an
error code.

Fixes: 520b6f7fbb6c ("sw_sync: Wait until the end")
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110150
