arm64: cpufeature: fold cpus_set_cap() into update_cpu_capabilities()
We only use cpus_set_cap() in update_cpu_capabilities(), where we
open-code an analgous update to boot_cpucaps.
Due to the way the cpucap_ptrs[] array is initialized, we know that the
capability number cannot be greater than or equal to ARM64_NCAPS, so the
warning is superfluous.
Fold cpus_set_cap() into update_cpu_capabilities(), matching what we do
for the boot_cpucaps, and making the relationship between the two a bit
clearer.
There should be no functional change as a result of this patch.
