Namjae Jeon 1c1bcf2d3e ksmbd: validate smb request protocol id ... This patch add the validation for smb request protocol id. If it is not one of the four ids(SMB1_PROTO_NUMBER, SMB2_PROTO_NUMBER, SMB2_TRANSFORM_PROTO_NUM, SMB2_COMPRESSION_TRANSFORM_ID), don't allow processing the request. And this will fix the following KASAN warning also.
