btrfs: send: remove old TODO regarding ERESTARTSYS
The whole send operation is restartable and handling properly a buffer
write may not be easy. We can't know what caused that and if a short
delay and retry will fix it or how many retries should be performed in
case it's a temporary condition.
The error value is returned to the ioctl caller so in case it's
transient problem, the user would be notified about the reason. Remove
the TODO note as there's no plan to handle ERESTARTSYS.
