Subject: classmate-laptop: should check for NULL as retval for rfkill_alloc

classmate-laptop: should check for NULL as retval for rfkill_alloc

rfkill_alloc returns NULL when it fails if RFKILL is enabled. When RFKILL is
disabled, its return value of ERR_PTR(-ENODEV) is OK to use as all rfkill
functions will work with it, as they are simply empty stubs.
