cxgb4: fix memory leak in cxgb4_init_ethtool_filters() error path

Browse source

[ Upstream commit 00ffb3724c ]

In the for loop used to allocate the loc_array and bmap for each port, a
memory leak is possible when the allocation for loc_array succeeds,
but the allocation for bmap fails. This is because when the control flow
goes to the label free_eth_finfo, only the allocations starting from
(i-1)th iteration are freed.

Fix that by freeing the loc_array in the bmap allocation error path.
