btrfs: fix an uninitialized variable warning in btrfs_log_inode
This fixes the following warning reported by gcc 10.2.1 under x86_64:
../fs/btrfs/tree-log.c: In function ‘btrfs_log_inode’:
../fs/btrfs/tree-log.c:6211:9: error: ‘last_range_start’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
6211 | ret = insert_dir_log_key(trans, log, path, key.objectid,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
6212 | first_dir_index, last_dir_index);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
../fs/btrfs/tree-log.c:6161:6: note: ‘last_range_start’ was declared here
6161 | u64 last_range_start;
| ^~~~~~~~~~~~~~~~
This might be a false positive fixed in later compiler versions but we
want to have it fixed.
