btrfs-progs: Return earlier for previous item

Follow kernel code to return earlier for btrfs_previous_item() function.

Before this patch, btrfs_previous_item() doesn't use its min_objectid to
exit, this makes caller to check key to exit, and if caller doesn't
check, it will iterate all previous item.

This patch will check min_objectid and type, to early return and save
some time.
