------------------

From: Moshe Shemesh <moshe@xxxxxxxxxxxx>


[ Upstream commit 461d5f1b59490ce0096dfda45e10038c122a7892 ]

mlx4_delete_all_resources_for_slave in resource tracker should free all
memory allocated for a slave.
While releasing memory of fs_rule, it misses releasing memory of
fs_rule->mirr_mbox.

Fixes: 78efed275117 ('net/mlx4_core: Support mirroring VF DMFS rules on both ports')
