svn rev #24303: trunk/src/lib/crypto/krb/

[lhoward@MIT.EDU]

http://src.mit.edu/fisheye/changelog/krb5/?cs=24303
Commit By: lhoward
Log Message:
krb5_k_make_checksum will use the mandatory checksum type if 0 is
passed in as the checksum type; however krb5_k_make_checksum_iov
does not support this. Add the same logic for the behaviour is
consistent.
