Namjae Jeon 330d900620 ksmbd: fix out of bounds in init_smb2_rsp_hdr() 
[ Upstream commit 536bb492d3 ]

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.
