cpuidle: ACPI: do not overwrite name and description of C0
commit c7e8bdf5872c5a8f5a6494e16fe839c38a0d3d3d upstream.
Fix a bug that leads to showing the name and description of C-state C0
as "<null>" in sysfs after the ACPI C-states changed (e.g. after AC->DC
or DC->AC
transition).
The function poll_idle_init() in drivers/cpuidle/driver.c initializes the
state 0 during cpuidle_register_driver(), so we better do not overwrite it
again with '\0' during acpi_processor_cst_has_changed().
