fixes ast_transfer stall until hangup if called with a channel that doesn't support transfers

Browse Source 
ast_transfer sets res to 0 if there is no technology transfer function,
but then tests for it to be negative before deciding to do an early exit.
As a result, it will will wait for an AST_CONTROL_TRANSFER message that
will never come.
