Explicitly switch to the new TSS by updating the current CPU's TSS selector
and reloading it in i386_extend_pcb() rather than trying to force a context
switch to reload the TSS via the TDF_NEEDRESCHED flag.  Optimizations to
avoid calling cpu_switch() when the new thread was identical to the old
thread defeated the attempt to force a TSS reload.  Explicitly loading the
new TSS is what we really want to do anyway.
