[CIFS] distinguish between Kerberos and MSKerberos in upcall
Properly handle MSKRB5 by passing sec=mskrb5 to the upcall so that the
spengo blob can be generated appropriately. Also, make
decode_negTokenInit prefer whichever mechanism is first in the list.
Needed for some NetApp servers, and possibly some older
versions of Windows which treat the two KRB5 mechanisms differently.
