Michael Brown e4593909a8 [pcbios] Do not switch to real mode to check for timer interrupt
The currticks() function is called at least once per TCP packet, and
so is performance-critical.  Switching to real mode just to allow the
timer interrupt to fire is expensive when running inside a virtual
machine, and imposes a significant performance cost.

Fix by enabling interrupts without switching to real mode.  This
results in an approximately 100% increase in download speed when
running under KVM.
