arm64: cpufeature: Fix CPU_OUT_OF_SPEC taint for uniform systems
Commit 3fde2999fac5 ("arm64: cpufeature: Don't dump useless backtrace on
CPU_OUT_OF_SPEC") changed the cpufeature detection code to use add_taint
instead of WARN_TAINT_ONCE when detecting a heterogeneous system with
mismatched feature support. Unfortunately, this resulted in all systems
getting the taint, regardless of any feature mismatch.
This patch fixes the problem by conditionalising the taint on detecting
a feature mismatch.
