Michael Brown 006d9f1f60 [undi] Support underlying UNDI devices that don't support interrupts
Some network cards do not generate interrupts when operated via the
UNDI API.  Allow for this by waiting for the ISR to be triggered only
if the PXE stack advertises that it supports interrupts.  When the PXE
stack does not advertise interrupt support, we skip the call to
PXENV_UNDI_ISR_IN_START and just poll the device using
PXENV_UNDI_ISR_IN_PROCESS.  This matches the observed behaviour of at
least one other PXE NBP (emBoot's winBoot/i), so there is a reasonable
chance of this working.
