Subject: bpf: make function xdp_do_generic_redirect_map() static
Patch-mainline: v4.16-rc1
Git-commit: c060bc6115b6a204cb60e6b03fe64135731bc6c8
References: bsc#1109837

The function xdp_do_generic_redirect_map() is only used in this file, so
make it static.

Clean up sparse warning:
net/core/filter.c:2687:5: warning: no previous prototype
for 'xdp_do_generic_redirect_map' [-Wmissing-prototypes]
