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.
