KVM: arm64: vgic: Fix detection of MI on no pending LR

As per the ARM GICv3 spec, the maintenance interrupt identified by
ICH_MISR_EL2.NP is asserted when it is enabled and no List register is
in pending state. This is further described in the document as "no List
registers with the State field set to 0b01 (pending)". By checking only
the pending bit of the LR (bit 62), KVM currently asserts the MI when
there are no LRs in "pending" or "pending and active" states.
Fix the detection logic to consider only the "pending" state.
