Summary
-------

It was possible that if realtime sipregs are used, that the varregs variable returned by ast_load_realtime() would not be freed. This patch aims to correct that.


This addresses bug ASTERISK-17792.
    https://issues.asterisk.org/jira/browse/ASTERISK-17792


Diffs
-----

  /branches/1.8/channels/chan_sip.c 338223 

Diff: https://reviewboard.asterisk.org/r/1465/diff


Testing
-------

It compiles. We return NULL in every case that ast_variables_destroy(varregs) is called, so there should be no chance of causing a problem with destroying the variable multiple times, etc.


Thanks,

Terry
