tls: fix sw_ctx leak

During setsockopt(SOL_TCP, TLS_TX), if initialization of the software
context fails in tls_set_sw_offload(), we leak sw_ctx. We also don't
reassign ctx->priv_ctx to NULL, so we can't even do another attempt to
set it up on the same socket, as it will fail with -EEXIST.

Fixes: 3c4d7559159b ('tls: kernel TLS support')
