x86/spectre: Check CONFIG_RETPOLINE in command line parser
commit 9471eee9186a46893726e22ebb54cade3f9bc043 upstream.
The spectre_v2 option 'auto' does not check whether CONFIG_RETPOLINE is
enabled. As a consequence it fails to emit the appropriate warning and sets
feature flags which have no effect at all.
Add the missing IS_ENABLED() check.
Fixes: da285121560e ("x86/spectre: Add boot time option to select Spectre v2 mitigation")
