cpufreq: powernv: Fix uninitialized lpstate_idx in gpstates_timer_handler()

lpstate_idx remains uninitialized in the case when elapsed_time
is greater than MAX_RAMP_DOWN_TIME.  At the end of rampdown the
global pstate should be equal to the local pstate.

Fixes: 20b15b766354 (cpufreq: powernv: Use PMCR to verify global and localpstate)
