ksmbd: fix out of bounds in init_smb2_rsp_hdr()
[ Upstream commit 536bb492d39bb6c080c92f31e8a55fe9934f452b ]
If client send smb2 negotiate request and then send smb1 negotiate
request, init_smb2_rsp_hdr is called for smb1 negotiate request since
need_neg is set to false. This patch ignore smb1 packets after ->need_neg
is set to false.
