KVM: nSVM: Track whether changes in L0 require MSR bitmap for L2 to be rebuilt
Similar to nVMX commit ed2a4800ae9d ("KVM: nVMX: Track whether changes in
L0 require MSR bitmap for L2 to be rebuilt"), introduce a flag to keep
track of whether MSR bitmap for L2 needs to be rebuilt due to changes in
MSR bitmap for L1 or switching to a different L2.
