Bugs: ASTERISK-24513
    https://issues.asterisk.org/jira/browse/ASTERISK-24513


Repository: Asterisk


Description
-------

After a blond transfer to a destination that then hangs up, the Local;1 channel would suffer a reference leak.  This was due to blond_nonfinal_enter() resetting the props->transfer_target to NULL as it unref'd the channel for itself, later preventing the attended_transfer_properties_destructor() from releasing it's own reference, which was inherited during ast_bridge_impart with INDEPDENDENT.

This change prevents props->transfer_target from being set to NULL, and thus eliminates the leak.

Thanks,
