This looks to me like a known and somewhat awkward bug/misfeature
where the mountpoint containing either the subvol being sent or the
target location for the receive is not a top-level mount, which causes
this error. i.e., this will (I think) fail:
# mount -o subvol=@foo /dev/sda1 /mnt
# btrfs send /mnt/@whatever | ...
Can you try again from within a subvolid=0 mount?
