Tag detection does not stop after screen off

There is a timing issue if a tag was detected just before
HOST sent screen off command. RF_INTF_ACTIVATED_NTF may still
be sent by NFCC (because it happened first). Then HOST will
activate the tag and keep the connection of tag.

The fix drop RF_INTF_ACTIVATED_NTF if screen turns off.
Update prevScreenState for NCi 1.0 devices when screen state change.
