btrfs: unify types for binary search variables 



The variables calculating where to jump next are using mixed in types
which requires some conversions on the instruction level. Using 'u32'
removes one call to 'movslq', making the main loop shorter.

This complements type conversion done in a724f313 ("btrfs: do
unsigned integer division in the extent buffer binary search loop")
