RDMA/rtrs-srv: Init wr_cnt as 1
[ Upstream commit 6f5d1b3016d650f351e65c645a5eee5394547dd0 ]
Fix up wr_avail accounting. if wr_cnt is 0, then we do SIGNAL for first
wr, in completion we add queue_depth back, which is not right in the
sense of tracking for available wr.
So fix it by init wr_cnt to 1.
