Avoid another null dereference in krb5_rd_cred()

In RFC 4120, the ticket client and server principal names are optional
in KrbCredInfo, but we have always required them to be present.  Add
checks to prevent null dereferences in krb5_rd_cred() if either name
is not specified.

[ghudson at mit.edu: folded check in with the end-of-list check; rewrote
comment and commit message]
