ksmbd: validate the zero field of packet header
The SMB2 Protocol requires that "The first byte of the Direct TCP
transport packet header MUST be zero (0x00)"[1]. Commit 1c1bcf2d3ea0
("ksmbd: validate smb request protocol id") removed the validation of
this 1-byte zero. Add the validation back now.
