btrfs-progs: consolidate setting of RAID1 stripes

Browse Source 
All 3 different RAID1 profiles use the same calculation mehod for the
number of used stripes.

Now that we do table lookups fo rmost of the allocation control
parameters, we can consolidate all 3 RAID1 profiles into a single branch
for the calculation.
