sfc: Break NAPI processing after one ring-full of TX completions
Currently TX completions do not count towards the NAPI budget. This
means a continuous stream of TX completions can cause the polling
function to loop indefinitely with scheduling disabled. To avoid
this, follow the common practice of reporting the budget spent after
processing one ring-full of TX completions.
