ath11k: Fix napi related hang

[ Upstream commit d943fdad7589653065be0e20aadc6dff37725ed4 ]

Similar to the same bug in ath10k, a napi disable w/out it being enabled
will hang forever.  I believe I saw this while trying rmmod after driver
had some failure on startup.  Fix it by keeping state on whether napi is
enabled or not.

And, remove un-used napi pointer in ath11k driver base struct.
