ppc/pnv: powerpc_excp: Do not discard HDECR exception when entering power-saving mode
The Hypervisor Decrementer exception should not be generated while the
CPU is in power-saving mode (see cpu_ppc_hdecr_excp()). However,
discarding the exception before entering the power-saving mode is
wrong since we would loose a previously generated HDEC.
