net/mlx4_core: Keep VLAN/MAC tables mirrored in multifunc HA mode
Due to HW limitations, indexes to MAC and VLAN tables are always taken
from the table of the actual port. So, if a resource holds an index to
a table, it may refer to different values during the lifetime of the
resource, unless the tables are mirrored. Also, even when
driver is not in HA mode the policy of allocating an index to these
tables is such to make sure, as much as possible, that when the time
comes the mirroring will be successful. This means that in multifunction
mode the allocation of a free index in a port's table tries to make sure
that the same index in the other's port table is also free.
