btrfs: factor out decide_stripe_size()
Factor out decide_stripe_size() from __btrfs_alloc_chunk(). This
function calculates the actual stripe size to allocate.
decide_stripe_size() handles the common case to round down the 'ndevs'
to 'devs_increment' and check the upper and lower limitation of 'ndevs'.
decide_stripe_size_regular() decides the size of a stripe and the size
of a chunk. The policy is to maximize the number of stripes.
This commit has no functional changes.
