Re: [U-Boot] [U-Boot, v2] fs: btrfs: Fix wrong comparison in logical to physical mapping

The comparison logical > item->logical + item->length in btrfs_map_logical_to_physical is wrong and should be instead logical >= item->logical + item->length For example, if item->logical = 4096 item->length = 4096 and we are looking for logical = 8192, it is not part of item (item is [4096, 8191]). But the comparison is false and we think we have found the correct item, although we should be searing in the right subtree.

This fixes some bugs I encountered.
