net/mlx5: Fix forward to next namespace

The steering tree is as follow (nic RX as example):
		   ---------
                   |root_ns|
		   ---------
			|
      	--------------------------------
    	|		|	       |
   ---------- 	   ----------      ---------
   |p(prio)0|	   |   p1   |      |   pn  |
   ----------	   ----------	   ---------
        |		|
 ----------------  ---------------
 |ns(e.g bypass)|  |ns(e.g. lag) |
 ----------------  ---------------
  |     |    |
----  ----  ----
|p0|  |p1|  |pn|
----  ----  ----
 |
----
|FT|
----

find_next_chained_ft(prio) returns the first flow table in the next
priority. If prio is a parent of a flow table then it returns the first
flow table in the next priority in the same namespace, else if prio
is parent of namespace, then it should return the first flow table
in the next namespace. Currently if the user requests to forward to
next namespace, the code calls to find_next_chained_ft with the prio
of the next namespace and not the prio of the namesapce itself.

Fixes: 9254f8ed ("net/mlx5: Add support in forward to namespace")
