ACPI: processor: idle: Add missing bounds check in flatten_lpi_states()

The inner loop in flatten_lpi_states() that combines composite LPI
states can increment flat_state_cnt multiple times within the loop.

The condition that guards this (checks bounds against ACPI_PROCESSOR
_MAX_POWER) occurs at the top of the outer loop. flat_state_cnt might
exceed ACPI_PROCESSOR_MAX_POWER if it is incremented multiple times
within the inner loop between outer loop iterations.

Add a bounds check after the increment inside the inner loop so that
it breaks out when flat_state_cnt reaches ACPI_PROCESSOR_MAX_POWER.
The existing check in the outer loop will then handle the warning.
