Subject: tls: Remove dead code in tls_sw_sendmsg
Patch-mainline: v4.19-rc1
Git-commit: 5a3611efe5b3095f348c892d040202b2ae969f4e
References: bsc#1109837

tls_push_record either returns 0 on success or a negative value on failure.
This patch removes code that would only be executed if tls_push_record
were to return a positive value.
