  xhci: Avoid DMA when ERSTBA is set to zero

The existing XHCI code reads the Event Ring Segment Table Base Address
Register (ERSTBA) every time when it is changed. However zero is its
default state so one would think that zero there means it is not in use.

This adds a check for ERSTBA in addition to the existing check for
the Event Ring Segment Table Size Register (ERSTSZ).

  usb: drop HOST_USB

Nowdays we use libusb for usb-host, so we don't have different code
for linux vs. bsd any more.  So there is little reason to have the
HOST_USB variable, we can just write things directly into the Makefile
and avoid a pointless indirection.
