net/ice/base: remove unused code in switch rule

Update a switch rule' action from "to VSI" to "to VSI List"
should only happen when the same rule has been programmed with
a different fwd destination. This is already handled by below
code block:

m_entry = ice_find_adv_rule_entry(...)
if (m_entry) {
...
ice_adv_add_update_vsi_list(...)
}

The following ice_update_pkt_fwd_rule is unnecessary and should be
removed due to:
1) If a switch rule's action is still to VSI, which means, it is
   the first time be issued,  we don't need to update it "to VSI

2) Actually the implementation does not match the comment, it still
   update the rule with "to VSI" action.

net/mlx5: introduce buffer size parameter for hairpin

When creating a hairpin queue, the total data size and the maximal
number of packets are interrelated. The differ is the stride size.
Larger buffer size means big packet like jumbo could be supported,
but in the meanwhile, it will introduce more cache misses and have a
side effect on the performance.
Now a new device parameter "hp_buf_log_sz" is introduced for
applications to set the total data buffer size (the logarithm value).
Then the maximal number of packets will also be calculated
automatically by this value.
Applications could also change this value to a larger one in order
to support larger packets in hairpin case. A smaller value will be
beneficial for memory consumption.
If it is not set, the default value will be used.
