While performing block transfer write in smb_ioport_writeb(),
'smb_index' is incremented and used to index smb_data[] array.
Check 'smb_index' value to avoid OOB access.
Note that this bug is exploitable by a guest to escape
from the virtual machine. However the commit which
introduced the bug was only made after the 3.0 release,
and so it is not present in any released QEMU versions.
