btrfs: don't call btrfs_handle_fs_error() after failure to delete orphan item

In btrfs_find_orphan_roots() we don't need to call btrfs_handle_fs_error()
if we fail to delete the orphan item for the current root. This is because
we haven't done anything yet regarding the current root and previous
iterations of the loop dealt with other roots, so there's nothing we need
to undo. Instead log an error message and return the error to the caller,
which will result either in a mount failure or remount failure (the only
contexts it's called from).
