[PATCH 1/2] net/mlx5: fix overridden flag in flow validation

[Michael Baum]

The AGE action can be implemented by either counters or ASO mechanism.
When user ask count action in the flow rule, AGE action is implemented
by the same counter. However, if user ask indirect count action, it
cannot be used for AGE.

The flow_dv_validate() function has a flag named "shared_count" which
indicates whether AGE action validate is depend on ASO support or not.
This flag is initialized to false and is updated if there is indirect
count action in the action list.
This flag is mistakenly set within the loop that reads the action list
and in each iteration it is reinitialized to false, regardless of the
existence of an indirect count action in the list.

This patch moves the flag initialization out of the loop.
