Shuhei Matsumoto fa2c6446fa bdev: Calculate max_copy once at bdev registration for fallback case 
Calculation of max copy size for fallback case includes division and is
costly. The result is constant for each bdev. Hence we can calculate it
only once and store it into bdev->max_copy at bdev registration.
Calculation of max copy size for fallback case is almost same as
calculation of max write zero size for fallback case. To reuse the
calculation, the helper function is named as bdev_get_max_write() and
has a num_bytes parameter.
