net: make symbol 'flush_works' static
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: 41852497a9205 ("net: batch calls to flush_all_backlogs()")
