net/openvswitch/flow.c: Replace rcu_dereference() with rcu_access_pointer()
The "rcu_dereference()" call is used directly in a condition.
Since its return value is never dereferenced it is recommended to use
"rcu_access_pointer()" instead of "rcu_dereference()".
Therefore, this patch makes the replacement.
The following Coccinelle semantic patch was used:

(
if(
(<+...

+ rcu_access_pointer
(...)

|
while(
(<+...
- rcu_dereference
+ rcu_access_pointer
(...)
...+>)) {...}
)
