[PATCH] cifs: primitive is not an asn1 class

[Chris Wright <chrisw@sous-sol.org>]

When verifying the decoded header before decoding the object identifier
(expecting a SPNEGO pseudo-mechanism oid), the test to verify it is a
primitive encoding is compared against the asn1 class.  Primitive is not a
class.  This brings check in line with similar check for krb/ntlmssp oid.
