====================
net/mlx5: LAG bug fixes

Three bug fixes by Shay in the mlx5 LAG subsystem.

Patch 1 fixes an off-by-one in the error rollback path of
mlx5_lag_create_single_fdb_filter(): the loop started from the
failed index i, potentially operating on uninitialized state or
double-tearing-down an entry that had already self-rolled-back.
The rollback should start from i - 1.

Patch 2 fixes a hang in mlx5_mpesw_work(): when
mlx5_lag_get_devcom_comp() returns NULL the function returned
early without calling complete(), blocking any caller waiting on
mpesww->comp indefinitely.

Patch 3 fixes a kernel crash during teardown when
mlx5_lag_get_dev_seq() returns an error because no device is
marked as master or the peer is no longer in the LAG. The peer
flow cleanup is now skipped instead of proceeding with a bad
pointer.

This series by Shay fixes three bugs in the mlx5 LAG subsystem.
