[PATCH 5.4 378/434] selftests: net: tls: remove recv_rcvbuf test

[Greg Kroah-Hartman]

From: Thadeu Lima de Souza Cascardo <cascardo@xxxxxxxxxxxxx>

[ Upstream commit 6dd504b0fd1039c6e5d391e97cf5c4ee592aefcb ]

This test only works when [1] is applied, which was rejected.

Basically, the errors are reported and cleared. In this particular case of
tls sockets, following reads will block.

The test case was originally submitted with the rejected patch, but, then,
was included as part of a different patchset, possibly by mistake.

Thanks Paolo Pisati for pointing out the original patchset where this
appeared.

Fixes: 65190f77424d (selftests/tls: add a test for fragmented messages)
