Ziwei XiaoandGreg Kroah-Hartman ff33be9cec gve: Fixes for napi_poll when budget is 0 ...

[ Upstream commit 278a370c17 ]

Netpoll will explicilty pass the polling call with a budget of 0 to
indicate it's clearing the Tx path only. For the gve_rx_poll and
gve_xdp_poll, they were mistakenly taking the 0 budget as the indication
to do all the work. Add check to avoid the rx path and xdp path being
called when budget is 0. And also avoid napi_complete_done being called
when budget is 0 for netpoll.
