Commit fa4491a6b667304 moved the permission check for io instructions
to the ->check_perm callback. It failed to copy the port value from RDX
register for string and "in,out ax,dx" instructions.

Fix it by reading RDX register at decode stage when appropriate.

Fixes FC8.32 installation.


Looks good.

We should really unify Src/Dst encoding and fetching.
