Namjae Jeon e01fc7caac ksmbd: validate smb request protocol id
[ Upstream commit 1c1bcf2d3ea061613119b534f57507c377df20f9 ]

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.
