Zilin Guan a5b44895da btrfs: release root after error in data_reloc_print_warning_inode() 
commit c367af440e upstream.

data_reloc_print_warning_inode() calls btrfs_get_fs_root() to obtain
local_root, but fails to release its reference when paths_from_inode()
returns an error. This causes a potential memory leak.

Add a missing btrfs_put_root() call in the error path to properly
decrease the reference count of local_root.

Fixes: b9a9a85059 ("btrfs: output affected files when relocation fails")
