net: dpaa: reduce number of synchronize_net() calls
In the function dpaa_napi_del(), we execute the netif_napi_del() for each cpu, which is actually a high overhead operation because each call to netif_napi_del() contains a synchronize_net(), i.e. an RCU operation. In fact, it is only necessary to call __netif_napi_del and use synchronize_net() once outside of the loop. This change is similar to commit 2543a6000e593a ("gro_cells: reduce number of synchronize_net() calls") and commit 5198d545dba8ad (" net: remove napi_hash_del() from driver-facing API") 5198d545db.
