When passing "test_suspend=mem" to the kernel:
PM: can't test 'mem' suspend state
and the suspend test is not run.
Commit 406e79385f3223d8 ("PM / sleep: System sleep state selection
interface rework") changed pm_labels[] from a contiguous NULL-terminated
array to a sparse array (with the first element unpopulated), breaking
the assumptions of the iterator in setup_test_suspend().
Iterate from PM_SUSPEND_MIN to PM_SUSPEND_MAX - 1 to fix this.
Fixes: 406e79385f3223d8 ("PM / sleep: System sleep state selection interface
rework")
