drbd: fix drbd epoch write count for ahead/behind mode
The sanity check when receiving P_BARRIER_ACK does expect all write requests with a given req->epoch to have been either all replicated, or all not replicated. Because req->epoch was assigned before calling maybe_pull_ahead(), this expectation was not met, leading to an off-by-one in the sanity check, and further to a "Protocol Error". Fix: move the call to maybe_pull_ahead() a few lines up, and assign req->epoch only after that.
