cxgb4: fix delete filter entry fail in unload path



Currently, the hardware TID index is assumed to start from index 0.
However, with the following changeset,

commit c2193999 ("cxgb4: add support for high priority filters")

hardware TID index can start after the high priority region, which
has introduced a regression resulting in remove filters entry
failure for cxgb4 unload path. This patch fix that.
