BUG/MINOR: cfgparse/stktable: fix error message on stktable_init() failure

As a result of copy paste error in 1b8e68e ("MEDIUM: stick-table: Stop
handling stick-tables as proxies."), postparsing stktable_init() failures
were reported as such for named peer tables:

   "Proxy 'table_name': failed to initialize stick table."

Now they are correctly reported like this:

   "Parsing [file:line]: failed to initialize 'table_name' stick-table."

This should be backported to every stable versions.
