Subject: ACPI: PM: Always print final debug message in acpi_device_set_power()
Patch-mainline: v5.19-rc1
Git-commit: 6dd4a29d26200d303d354ee8fc806113b5fcc882
References: jsc#PED-1408

acpi_device_set_power() prints debug messages regarding its outcome
(whether or not the power state has been changed and how) in all
cases except when the device whose power state is being changed to D0
is in that power state already.

Make acpi_device_set_power() print a final debug message in that case
too and while at it, fix the indentation of the "end" label in this
function.
