accel: Do not set CPUState::can_do_io in non-TCG accels

Browse Source 
'can_do_io' is specific to TCG. It was added to other
accelerators in 626cf8f4c6 ("icount: set can_do_io outside
TB execution"), then likely copy/pasted in commit c97d6d2cdf
("i386: hvf: add code base from Google's QEMU repository").
Having it set in non-TCG code is confusing, so remove it from
QTest / HVF / KVM.

Fixes: 626cf8f4c6 ("icount: set can_do_io outside TB execution")
