replay: Simplify setting replay blockers

Browse Source 
replay_add_blocker() takes an Error *.  All callers pass one created
like this:

    error_setg(&blocker, QERR_REPLAY_NOT_SUPPORTED, "some feature");

Folding this into replay_add_blocker() simplifies the callers, losing
a bit of generality we haven't needed in more than six years.

Since there are no other uses of macro QERR_REPLAY_NOT_SUPPORTED,
replace the remaining one by its expansion, and drop the macro.
