[PATCH] cifs: spnego: add ';' in HOST_KEY_LEN

From: Anastasia Belova
Date: Mon Nov 13 2023 - 09:53:20 EST


"host=" should start with ';' (as in cifs_get_spnego_key)
So its length should be 6.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: 7c9c3760b3a5 ("[CIFS] add constants for string lengths of keynames in SPNEGO upcall string")
