target-i386: Fix I/O bitmap checks for in/out

Commit 1b90d56e changed the implementation of in/out imm to not assign
the accessed port number to cpu_T[0] as it appeared unnecessary.
However, currently gen_check_io() makes use of cpu_T[0] to implement the
I/O bitmap checks, so it's in fact still used and the change broke the
check, leading to #GP in legitimate cases (and probably also allowing
access to ports that shouldn't be allowed).

This patch reintroduces the missing assignment for these cases.
