btrfs: consolidate btrfs_previous_item ret val handling in btrfs_shrink_device
Instead of having three 'if' to handle non-NULL return value consolidate
this in one 'if (ret)'. That way the code is more obvious:
- Always drop delete_unused_bgs_mutex if ret is not NULL
- If ret is negative -> goto done
- If it's 1 -> reset ret to 0, release the path and finish the loop.
