ideapad: read brightness setting on brightness key notify
BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=25922 On ideapad Y530, the brightness key notify will be blocked if the last notify is not responsed by getting the brightness value. Read value when we get the notify shall fix the problem and will not have any difference on other ideapads.
