ACPI: processor: idle: Remove redundant cstate check in acpi_processor_power_init

[ Upstream commit db19103ea847ed139da59a2fb71773081c12cd40 ]

The function acpi_processor_cstate_first_run_checks() is responsible
for updating max_cstate and performing initial hardware validation.

Currently, this function is invoked within acpi_processor_power_init().
However, the initialization flow already ensures this is called during
acpi_processor_register_idle_driver().  Therefore, the call in
acpi_processor_power_init() is redundant and effectively performs no work,
so remove it.
