cxgb4/chtls: fix ULD connection failures due to wrong TID base
Currently, the hardware TID index is assumed to start from index 0. However, with the following changeset, commit c21939998802 ("cxgb4: add support for high priority filters") hardware TID index can start after the high priority region, which has introduced a regression resulting in connection failures for ULDs. So, fix all related code to properly recalculate the TID start index based on whether high priority filters are enabled or not.
