net: tls: set MSG_SPLICE_PAGES consistently
We used to change the flags for the last segment, because
non-last segments had the MSG_SENDPAGE_NOTLAST flag set.
That flag is no longer a thing so remove the setting.
Since flags most likely don't have MSG_SPLICE_PAGES set
this avoids passing parts of the sg as splice and parts
as non-splice. Before commit under Fixes we'd have called
tcp_sendpage() which would add the MSG_SPLICE_PAGES.
Why this leads to trouble remains unclear but Tariq
reports hitting the WARN_ON(!sendpage_ok()) due to
page refcount of 0.
Fixes: e117dcfd646e ("tls: Inline do_tcp_sendpages()")
