From: Chuck Lever <chuck.lever@xxxxxxxxxx>
[ Upstream commit dda9a951dd6dd6073bbaf2c8d3119da2f8fe2d5b ]
I noticed that when rpcrdma_xprt_connect() returns -ENOMEM,
instead of retrying the connect, the RPC client kills the
RPC task that requested the connection. We want a retry
here.
Fixes: cb586decbb88 ("xprtrdma: Make sendctx queue lifetime the same as connection lifetime")
