Most of our completers used the pattern:
if ((nITEM = virITEMListAll()) < 0)
   return NULL;

but the virDomainSnapshot and virStorageVolume completers were instead
using goto error because of a prior allocation. If the ListAll fails
with -1, the cleanup label was running a loop of 'size_t i < int
nITEM', which is an extreme waste of CPU cycles.

This one is a bug fix, so worth having in 5.2.
