btrfs-progs: btrfs_list_get_path_rootid error handling
btrfs_list_get_path_rootid() tries to return a negative number on error, but it's a u64 function. Callers which test for a return < 0 will never see an error. Change the function to fill in the rootid via a pointer, and then return a simple int as error. Signed-off-by: Eric Sandeen <sandeen@redhat.com>
