Konrad Rzeszutek Wilk 3389bb8bf7 xen/blkback: Make optional features be really optional.
They were using the xenbus_dev_fatal() function which would
change the state of the connection immediately. Which is not
what we want when we advertise optional features.

So make 'feature-discard','feature-barrier','feature-flush-cache'
optional.

[v1: Made the discard function void and static]
