    rfkill: allow toggling soft state in sysfs again
    
    Apparently there actually _are_ tools that try to set
    this in sysfs even though it wasn't supposed to be used
    this way without claiming first. Guess what: now that
    I've cleaned it all up it doesn't matter and we can
    simply allow setting the soft-block state in sysfs.

Didn't make -rc4, should be in -rc5.
