Merge branch 'net-ipa-dont-cache-channel-state'

Alex Elder says:

====================
net: ipa: don't cache channel state

This series removes a field that holds a copy of a channel's state
at the time it was last fetched.  In principle the state can change
at any time, so it's better to just fetch it whenever needed.  The
first patch is just preparatory, simplifying the arguments to
gsi_channel_state().
