SUNRPC: xprt_complete_bc_request must also decrement the free slot count
Calling xprt_complete_bc_request() effectively causes the slot to be allocated, so it needs to decrement the backchannel free slot count as well. Fixes: 0d2a970d0ae5 ("SUNRPC: Fix a backchannel race") Signed-off-by: Trond Myklebust <trond.myklebust@primarydata.com>
