Corrections to the extresist code. Some of the changes are just 

text formatting.  Made one critical correction to ResGetDevice() to
pass the device type;  otherwise, devices on different planes (e.g.,
MiM caps) with the same coordinate will always return the device on
the lowest plane, leading to incorrect results and an eventual crash
when the device record is free'd twice.
