mac80211: Replace {sw, hw}_scanning variables with a bitfield

Browse Source 
Use a bitfield to store the current scan mode instead of two boolean
variables {sw,hw}_scanning. This patch does not introduce functional
changes but allows us to enhance the scan flags later (for example
for background scanning).
