rt2x00: convert rt2x00_desc_read return type
This is a semi-automated conversion to change rt2x00_desc_read to return
the register contents instead of passing them by value, resulting in
much better object code. The majority of the patch was done using:
sed -i 's:\(\<rt2x00_desc_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
-i 's:\(\<_rt2x00_desc_read\>(.*, .*\), &\(.*\));:\2 = \1);:' \
