rust: cpufreq: Add CPUFREQ_TABLE_END as last table entry in TableBuilder::to_table

Browse source

The `TableBuilder::to_table` function adds `Hertz(c_ulong::MAX).as_khz()`
as the last frequency entry in the frequency table.
But the C API expects the last entry to have frequency set to
`CPUFREQ_TABLE_END` which is `~1u` as per include/linux/cpufreq.h.

Fix this by setting the last frequency entry to `CPUFREQ_TABLE_END`
instead of `Hertz(c_ulong::MAX).as_khz()`.
