[PATCH] reset tss->io_bitmap_owner in sys_ioperm()



my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID
d5cd4aad) introduced a problem with a
program (DOSEMU) that called ioperm after already doing some port i/o.

The problem is that a process switch return causes tss->io_bitmap_base
to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the
io bitmap) never triggers.

This fixes that regression.
