Subject: [PATCH net-next 3/3] net: core: fix wrong linkage for ptype_base and ptype_all symbols

In commit 900ff8c6 ("net: move procfs code to net/core/net-procfs.c"),
it changed the correct linkage of ptype_base and ptype_all symbols to
the wrong one in net/core/dev.c, yet failed to change to the correct
linkage of those two in net/core/net-procfs.c.

Fix the wrong linkage by setting static specifier to both sets of the
symbols so that they could have coherent internal linkage by themselves
to avoid interference with each other.
