btrfs: Add raid56 support for updating
num_tolerated_disk_barrier_failures in btrfs_balance
Code for updating fs_info->num_tolerated_disk_barrier_failures in
btrfs_balance() lacks raid56 support.
Reason:
Above code was wroten in 2012-08-01, together with
btrfs_calc_num_tolerated_disk_barrier_failures()'s first version.
Then, btrfs_calc_num_tolerated_disk_barrier_failures() got updated
later to support raid56, but code in btrfs_balance() was not
updated together.
Fix:
Merge above similar code to a common function:
btrfs_get_num_tolerated_disk_barrier_failures()
and make it support both case.
It can fix this bug with a bonus of cleanup, and make these code
never in above no-sync state from now on.
