ksmbd: Replace one-element array with flexible-array member

[ Upstream commit 11d5e2061e973a8d4ff2b95a114b4b8ef8652633 ]

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.
