Alan Somers 03e7a2be06 Speed up "zpool import" in the presence of many zvols
By default, zpools may not be backed by zvols (that can be changed with the
"vfs.zfs.vol.recursive" sysctl). When that sysctl is set to 0, the kernel
does not attempt to read zvols when looking for vdevs. But the zpool command
still does. This change brings the zpool command into line with the kernel's
behavior. It speeds "zpool import" when an already imported pool has many
zvols, or a zvol with many snapshots.
