[CPUFREQ] Fix the bug in duplicate freq elimination code in acpi-cpufreq
Fix the bug in duplicate states elimination in acpi-cpufreq. Bug: Due to duplicate state elimiation in the loop earlier, the number of valid_states can be less than perf->state_count, in which case freq_table was ending up with some garbage/uninitialized entries in the table.
