Fix tidl error handling code

Fix tidl error handling code

- Issue:
TIDL functions always return -1 even if those are failed by various
reasons.

- Solution:
The code generated by tidlc uses 'set_last_result()' and 'get_last_result()'
function for handling exception. Thus, the caller of those code should
check the error code of 'get_last_result()' first. However, current code
only check return value of each functions.
This patch adds logic for check the error from 'get_last_result()'.
Through this change, framework can handle error from tidl code properly.
