[PATCH 01/10] btrfs-progs: Drop ext_ref parameter from find_inode_ref

[Nikolay Borisov <nborisov@suse.com>]

This is a boolean parameter which signals whether the fs has the
EXTENDED_IREF feature flag toggled or not. Since a reference to fs_info
can be obtained there is no need to pollute the interface.
