SCSI emulation: should tell the guest that we actually support thin provisioning
Signed-off-by: Ronnie Sahlberg <ronniesahlberg@gmail.com> [Actually, we should report it only if discard_granularity is nonzero. Older SBC drafts assigned 0 to thin provisioning and 1 to thick (resource-provisioned, they call it). Newer drafts assign respectively 1 and 2 - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
