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.
