plugin:python: check asprintf() errors

The code was validating the string but the man page for asprintf(3)
says clearly:

--------
If memory allocation wasn't possible, or some other error occurs,
these functions  will return -1, and the contents of strp are undefined.
--------

So, we cannot really rely on the returned string pointer.
