[Bug-hurd] Problem with dev/glue/block.c (checkin 1.4)

[Brent Fulgham]

The latest mask additions to dev/glue/block.c seem to have
caused some problems (at least with my hardware).

I haven't yet debugged the cause, but it seems that the
mask is not being initialized properly, which causes the
Hurd to be unable to mount IDE drives properly (i.e., a
formerly working system will now be unable to boot,
complaining that the drive is not available.).

I'll try to collect more data, but commenting out
the "& mask" from each of the lines it was added to
corrects the problem.

Regards,
