ksmbd: fix out-of-bound read in smb2_write
commit 5fe7f7b78290638806211046a99f031ff26164e1 upstream. ksmbd_smb2_check_message doesn't validate hdr->NextCommand. If ->NextCommand is bigger than Offset + Length of smb2 write, It will allow oversized smb2 write length. It will cause OOB read in smb2_write.
