[PATCH 05/14] sd: simplify the ZBC case in provisioning_mode_store

[Martin K. Petersen]

Christoph,

> Don't reset the discard settings to no-op over and over when a user
> writes to the provisioning attribute as that is already the default
> mode for ZBC devices.  In hindsight we should have made writing to
> the attribute fail for ZBC devices, but the code has probably been
> around for far too long to change this now.
