[net-next PATCH 3/4] netdev: replace napi_reschedule with napi_schedule

[Christian Marangi <ansuelsmth@gmail.com>]

Now that napi_schedule return a bool, we can drop napi_reschedule that
does the same exact function. The function comes from a very old commit
bfe13f54f502 ("ibm_emac: Convert to use napi_struct independent of struct
net_device") and the purpose is actually deprecated in favour of
different logic.

Convert every user of napi_reschedule to napi_schedule.
