[libvirt] [PATCH] SCSI storage: Initialise the pool size parameters to zero while refreshing

[Nitesh Konkar]

If the pool creation thread happens to detect the luns 
in the scsi target,the size parameters will be populated 
as part of the refresh called from storagePoolCreate().
The commit <4a85bf3e2f> added additional refresh for 
SCSI which should also have these values initialised 
to zero, otherwise the values would appear exactly double.
A separate refresh would correct the values, but without 
an explicit pool-refresh, the allocation/capacity would 
appear exactly double after pool-create.
