net: make symbol 'flush_works' static

Browse Source 
The sparse tool complains as follows:

net/core/dev.c:5594:1: warning:
 symbol '__pcpu_scope_flush_works' was not declared. Should it be static?

'flush_works' is not used outside of dev.c, so marks
it static.

Fixes: 41852497a9 ("net: batch calls to flush_all_backlogs()")
