asix-sigma: check sdi before dereferencing a NULL pointer

The asix-sigma config_list() routine unconditionally dereferenced the
'sdi' pointer, which could be NULL. Properly check before dereferencing.
This issue was introduced in commit eabf9ca630f4. How to reproduce:

  $ sigrok-cli -d asix-sigma --show
