cfg80211: consolidate passive-scan and no-ibss flags
These two flags are used for the same purpose, just
combine them into a no-ir flag to annotate no initiating
radiation is allowed.
Old userspace sending either flag will have it treated as
the no-ir flag. To be considerate to older userspace we
also send both the no-ir flag and the old no-ibss flags.
Newer userspace will have to be aware of older kernels.
Update all places in the tree using these flags with the
following semantic patch:

remove duplicates and to fix some indentation.
