x86/HVM: fix boundary check in hvmemul_insn_fetch() (again)

Commit 5a992b670b ("x86/hvm: Fix boundary check in
hvmemul_insn_fetch()") went a little too far in its correction to
commit 0943a03037 ("x86/hvm: Fixes to hvmemul_insn_fetch()"): Keep the
start offset check, but restore the original end offset one.
