[PATCH 01/11] btrfs-progs: check: Remove root argument from delete_extent_records

[Nikolay Borisov <nborisov@suse.com>]

This function is always passed the extent_root as "root" parameter. In
turn it uses the root parameter to mostly access fs_info and performs
only a single call to btrfs_update_block_group where it passses the
passed root. This is all redundant since fs_info can be referenced
from the transaction handle and in turn extent_root can be referenced
from the fs_info. So do that to simplify the function's signature.
