Silence a scan-build warning in dns_rbt_addname()

Browse Source 
Clang Static Analyzer is unable to grasp that when dns_rbt_addnode()
returns ISC_R_EXISTS, it always sets the pointer passed to it via its
'nodep' parameter to a non-NULL value.  Add an extra safety check in the
conditional expression used in dns_rbt_addname() to silence that
warning.
