A kludge to always give the driver a second chance to attach the cbb device.

A kludge to always give the driver a second chance to attach the cbb device.

Similar to the following part of FreeBSD rev 1.66 by imp:
  o Remove bogus checks when reallocating memory for the registers.  They
    weren't needed and turned out to be completely bogus.

  This lets me load/unload pccard with a pccard in a slot and have the
  child correctly detach/attach.  This should help people that have wi
  in their kernel, but that kldload cbb and pccard, for example.
