cpuidle: PSCI: Move the `has_lpi` check to the beginning of the function

commit 01f6c7338ce267959975da65d86ba34f44d54220 upstream.

Currently the first thing checked is whether the PCSI cpu_suspend function
has been initialized.

Another change will be overloading `acpi_processor_ffh_lpi_probe` and
calling it sooner.  So make the `has_lpi` check the first thing checked
to prepare for that change.
