rABCd492f70d97d3: net: simplify the call to vProcessMsg.splice()

Summary

At the time when

cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), it);

is called, it is certainly pnode->vRecvMsg.end() which makes the
call equivalent to:

cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg, pnode->vRecvMsg.begin(), pnode->vRecvMsg.end());

which is equivalent to:

cpp
pnode->vProcessMsg.splice(pnode->vProcessMsg.end(), pnode->vRecvMsg);

Thus, use the latter. Further, maybe irrelevant, but the latter has
constant complexity while the original code is O(length of vRecvMsg).

This is a backport of core#26888
Depends on D18243
