rfkill: allow toggling soft state in sysfs again

Apparently there actually _are_ tools that try to set

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.
