Subject: [PATCH][next] smb: Replace one-element array with flexible-array
 member

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in struct smb_negotiate_req.

This results in no differences in binary output.
