40cab44b90 net/sched: fix retpoline wrapper compilation on configs without tc filters
Rudi reports a compilation failure on x86_64 when CONFIG_NET_CLS or
CONFIG_NET_CLS_ACT is not set but CONFIG_RETPOLINE is set.
A misplaced '#endif' was causing the issue.

Fixes: 7f0e810220 ("net/sched: add retpoline wrapper for tc")

7f0e810220 net/sched: add retpoline wrapper for tc
On kernels using retpoline as a spectrev2 mitigation,
optimize actions and filters that are compiled as built-ins into a direct call.

On subsequent patches we expose the classifiers and actions functions
and wire up the wrapper into tc.
