btrfs: rename clean_io_failure and remove extraneous args

This is exported, so rename it to btrfs_clean_io_failure.  Additionally
we are passing in the io tree's and such from the inode, so instead of
doing all that simply pass in the inode itself and get all the
components we need directly inside of btrfs_clean_io_failure.
