Subject: Add skip_balance option to BTRFS mounts
References: bsc#1108255
Upstream: merged
Git-commit: f46c26fcf879f368726acf650c43eacde909dc9d

If a crash happens while a balance operation is being performed on a
target btrfs filesystem, then this balance operation is resumed in
the kdump environment, which is not desirable. Skip it by adding a
'skip_balance' mount option to the kdump initrd.
