Fix krb5_cccol_have_content() bad pointer free

krb5_cccol_have_content() calls krb5_cc_get_principal() within a loop,
and frees the resulting principal on success or failure.  Set princ to
null before each call to ensure we don't free a dangling pointer.

[ghudson@mit.edu: rewrote commit message; moved assignment for greater
clarity]
