[PATCH] PM: check sysdev_suspend(PMSG_FREEZE) return value

[Bjorn Helgaas <bjorn.helgaas@hp.com>]

Check the return value of sysdev_suspend().  I think this was a typo.
Without this change, the following "if" check is always false.
I also changed the error message so it's distinguishable from the
similar message a few lines above.
