arm64: cpufeatures: Fix FEAT_NV check when checking for FEAT_NV1
Using this_cpu_has_cap() has the potential to go wrong when
used system-wide on a preemptible kernel. Instead, use the
__system_matches_cap() helper when checking for FEAT_NV in the
FEAT_NV1 probing helper.
Fixes: 3673d01a2f55 ("arm64: cpufeatures: Only check for NV1 if NV is present")
