ipv6: fib: hide unused 'pn' variable

Browse source

[ Upstream commit 74043489fc ]

When CONFIG_IPV6_SUBTREES is disabled, the only user is hidden, causing
a 'make W=1' warning:

net/ipv6/ip6_fib.c: In function 'fib6_add':
net/ipv6/ip6_fib.c:1388:32: error: variable 'pn' set but not used [-Werror=unused-but-set-variable]

Add another #ifdef around the variable declaration, matching the other
uses in this file.

Fixes: 66729e18df ("[IPV6] ROUTE: Make sure we have fn->leaf when adding a node on subtree.")
