[PATCHv2] phyp: don't steal storage management from other drivers

[Eric Blake <eblake@xxxxxxxxxx>]

Fix regression introduced in commit a4a287242 - basically, the
phyp storage driver should only accept the same URIs that the
main phyp driver is willing to accept.  Blindly accepting all
URIs meant that the phyp storage driver was being consulted for
'virsh -c qemu:///session pool-list --all', rather than the
qemu storage driver, then since the URI was not for phyp, attempts
to then use the phyp driver crahsed because it was not initialized.

* src/phyp/phyp_driver.c (phypStorageOpen): Only accept connections
already open to a phyp driver.
---

diff from v1 - assume that for the secondary storage driver, the
master driver has already been initialized and we don't have to
reparse the URI.

Definitely much shorter, once I realized I should be copying from
esx_storage_driver.c as a prior example.
