[libvirt] [PATCH 4/4] domblkinfo: Check for NFS FS Type

[John Ferlan]

Similar to the vol-info code, check if the target device for the
blkinfo fetch is an NFS volume and return the st_size value rather than
calculating the size based on st_blksize and DEV_BSIZE.

Prior to the change a 40M target device would display:

Capacity:       41943040
Allocation:     126976
Physical:       126976

With the change it will display:

Capacity:       41943040
Allocation:     41943040
Physical:       41943040
