[PATCH v2 4/6] btrfs: don't pass fs_info to describe_relocation

[Johannes Thumshirn <jth@kernel.org>]

From: Johannes Thumshirn <johannes.thumshirn@wdc.com>

In describe_relocation() the fs_info is only needed for printing
information via btrfs_info() and can easily be accessed via the passed
in 'struct btrfs_block_group'.

So we can savely remove the fs_info parameter.
