[PATCH] PM: Make warning in suspend_test_finish() less likely to happen

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rjw@sisk.pl>

Increase TEST_SUSPEND_SECONDS to 10 so the warning in
suspend_test_finish() doesn't annoy the users of slower systems so
much.

Also, make the warning print the suspend-resume cycle time, so
that we know why the warning actually triggered.

Patch prepared during the hacking session at the Kernel Summit in
Tokyo.
