[PATCH net] cxgb4: Fix offset when clearing filter byte counters

[PATCH net] cxgb4: Fix offset when clearing filter byte counters

[Ganji Aravind]

Pass the correct offset to clear the stale filter hit
bytes counter. Otherwise, the counter starts incrementing
from the stale information, instead of 0.

Fixes: 12b276fbf6e0 ("cxgb4: add support to create hash filters")
