target/i386/hvf: fix the declaration of hvf_handle_io

Browse Source 
There is a conflicting declaration for hvf_handle_io in x86_emu.c.  The type of
the first argument is wrong.  There has never been a problem because the first
argument is not used in hvf_handle_io.

That being said, the code shouldn't contain such an error. Use the proper
declaration from hvf-i386.h.

Take the chance to change the first argument's type to be CPUState.
