[PATCH 02/14] ubd: untagle discard vs write zeroes not support handling

[Martin K. Petersen]

Christoph,

> Discard and Write Zeroes are different operation and implemented
> by different fallocate opcodes for ubd.  If one fails the other one
> can work and vice versa.
>
> Split the code to disable the operations in ubd_handler to only
> disable the operation that actually failed.
