net/smc: abort CLC connection in smc_release
In case of a non-blocking SMC socket, the initial CLC handshake is performed over a blocking TCP connection in a worker. If the SMC socket is released, smc_release has to wait for the blocking CLC socket operations (e.g., kernel_connect) inside the worker. This patch aborts a CLC connection when the respective non-blocking SMC socket is released to avoid waiting on socket operations or timeouts.
