Jan Beulich db108b67d8 xen-blkback: don't leak persistent grants from xen_blkbk_map() 
commit a846738f8c upstream.

The fix for XSA-365 zapped too many of the ->persistent_gnt[] entries.
Ones successfully obtained should not be overwritten, but instead left
for xen_blkbk_unmap_prepare() to pick up and put.

This is XSA-371.
