[PATCH] pipeline: fix annotation checks

[Cristian Dumitrescu]

The checks for the table-only and default-only annotations were
incorrect, as they were using the pipeline action ID instead of the
table action ID for retrieving the table action info. These checks are
now corrected and pushed into the internal table_entry_check()
function.

Fixes: cd79e0205824 ("pipeline: support action annotations")
