PM: hibernate: fix __setup handler error handling
[ Upstream commit ba7ffcd4c4da374b0f64666354eeeda7d3827131 ] If an invalid value is used in "resumedelay=<seconds>", it is silently ignored. Add a warning message and then let the __setup handler return 1 to indicate that the kernel command line option has been handled.
