[PATCH] pm / core bugfix: report error return from suspend_enter

[MyungJoo Ham]

The current implementation of suspend-to-RAM returns 0 if there is an
error from suspend_enter() because suspend_devices_and_enter() ignores
the return value from suspend_enter(). This patch addresses this issue
and properly keep the error return from suspend_enter() and let
suspend_devices_and_enter relay the error return.
