It returned a constant value so it didn't actually
mean anything.

While here also make it static.

Identified by cppcheck.

Interesting find.  I guess someone in some distant past assumed that
we might see failure modes for prepare_push_reply()...

stare-at-code says "this must be fine", but as it affects server code,
I subjected it to the t_server testbed which does excercise PUSH quite
a bit :-) - and everything still works.

Your patch has been applied to the master branch.
