ArmPkg: ArmPsciMpServicesDxe: Fix MPIDR usage from CoreInfo

Browse source 
The `GET_MPIDR_AFFINITY_BITS` macro masks MT_BIT in ArmReadMpidr (), but
`CoreInfo[Index].Mpidr` wasn't masked by the same macro which causes a
mismatch even if it is the same MPIDR value.

This change uses the same `GET_MPIDR_AFFINITY_BITS` macro for
`CoreInfo[Index].Mpidr` to fix the core index searching logic.
