wmbiff: Remove unnecessary loop.
The last release of wmbiff included a patch by Nye Liu from Debian
bug #917467 [1]. However, the second part of that patch is not necessary.
From Andreas Metzler's comment
I am not sure about the second part of the patch. I understand wmbiff
breaking on GNUTLS_E_AGAIN from gnutls_read, because this only started
to happen recently (with TLS1.3) on blocking sockets.
What I do not get from my rudimentary understanding C programmimg is the
second part, this is in the else of "if (scs->tls_state)", so, afaiui for
non-encrypted connections. Is the change necessary there at all, is it
the right thing to retry read on EAGAIN then?
We revert the second part of the patch.
