[krbdev.mit.edu #8750] Resource leak in ktutil_add()

[Bean Zhang via RT]

Hi Team,

In ktutil_add() of krb5-1.16.1/src/kadmin/ktutil/ktutil_funcs.c,
In the first 3 places to call malloc(), if the first place calling malloc() succeeds,
then the 2nd or 3rd place fails, it just returns ENOMEM without freeing the memory allocated in first place.

Could someone help to take a look?

Thanks,
Bean
