sunvnet: bug fixes

This patch series has a coding-style fix and a bug fix.

The coding style fix (patch 1) is the extra indentation flagged by Ben Hutchings:
http://marc.info/?l=linux-netdev&m=141529243409594&w=2

The bugfix (patch 2) is the following:
when vnet_event_napi() is called as part of napi_resume (i.e., continuation of a previous NAPI read that was truncated due to budget constraints), and then finds no more packets to read, the code was trying to avoid an additional trip through ldc_rx as an optimization. However, when this corner case happens, we would need to reset a number of dring state bits such as rcv_nxt carefully, which quickly becomes complex and hacky. The cleaner solution is to just roll back to vnet_poll, re-enable interrupts and set up dring state as was done in the pre-NAPI version of the driver.

Sowmini Varadhan (2):
Fix indentation in maybe_tx_wakeup()
Return from vnet_napi_event() if no packets to read
