Rajvi JingarandGreg Kroah-Hartman dd691e300d platform/x86/intel/pmc: Fix hang in pmc_core_send_ltr_ignore() ...

[ Upstream commit fbcf67ce5a ]

For input value 0, PMC stays unassigned which causes crash while trying
to access PMC for register read/write. Include LTR index 0 in pmc_index
and ltr_index calculation.
