net/mlx4_core: Add missed mlx4_free_cmd_mailbox()

Browse Source 
[ Upstream commit 8eb65fda4a6dbd59cd5de24b106a10b6ee0d2176 ]

mlx4_do_mirror_rule() forgets to call mlx4_free_cmd_mailbox() to
free the memory region allocated by mlx4_alloc_cmd_mailbox() before
an exit.
Add the missed call to fix it.

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