storage: reject negative indices

Browse Source 
Commit f22b7899 stumbled across a difference between 32-bit and
64-bit platforms when parsing "-1" as an int.  Now that we've
fixed that difference, it's time to fix the testsuite.

* src/util/virstoragefile.c (virStorageFileParseChainIndex):
Require a positive index.
