tcg: fix cpu_io_recompile
cpu_io_recompile() function was broken by
the commit 9b990ee5a3cc6aa38f81266fb0c6ef37a36c45b9. Instead of regenerating
the block starting from PC of the original block, it just set the instruction
counter for TCG. In most cases this was unnoticed, but in icount mode
there was an exception for incorrect usage of CF_LAST_IO flag.
This patch recovers recompilation of the original block and also
configures translation for executing single IO instruction which
caused a recompilation.
