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



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.
