Subject: [PATCH] tls: Fixed uninitialised vars warning
In tls_sw_sendmsg() and tls_sw_sendpage(), it is possible that the
uninitialised variable 'ret' gets passed to sk_stream_error(). So
initialise local variable 'ret' to '0. The warnings were detected by
'smatch' tool.
Fixes: a42055e8d2c3 ("net/tls: Add support for async encryption")
