modules_k/userblacklist : check_blacklist function uses globalblacklist_table as data source if no parameter is given.

Globalblacklist_table parameter was not used at all in the userblacklist module, the check_blacklist funtion always needing one parameters and the db table. This is not mandatory anymore, as the check_blacklist function with no parameters will use the globalblacklist_table
