netmap: Ignore errors in CSB_WRITE()
The CSB_WRITE() and _READ() macros respectively write to and read from
userspace memory and so can in principle fault. However, we do not
check for errors and will proceed blindly if they fail. Add assertions
to verify that they do not.
This is in preparation for annotating copyin() and related functions
with __result_use_check.
