KVM: arm64: Drop %pB on nVHE panic when stage-2 is active
With pKVM, the host stage-2 is lazily mapped. kallsyms, accessed via
the modifier %pB is therefore potentially unmapped. If the hyp panic
occurred while the host stage-2 lock was held, handling this fault
deadlocks.
Skip %pB formatting unless the host stage-2 is disabled.
