arm64: Run ARCH_WORKAROUND_2 enabling code on all CPUs
Commit 606f8e7b27bf ("arm64: capabilities: Use linear array for detection and verification") changed the way we deal with per-CPU errata by only calling the .matches() callback until one CPU is found to be affected. At this point, .matches() stop being called, and .cpu_enable() will be called on all CPUs. This breaks the ARCH_WORKAROUND_2 handling, as only a single CPU will be mitigated. In order to address this, forcefully call the .matches() callback from a .cpu_enable() callback, which brings us back to the original behaviour.
