[libvirt] [PATCH] cmdPoolDiscoverSources: initialize earlier to avoid FP from clang

[Jim Meyering <jim@xxxxxxxxxxxx>]

This change hoists the initialization of srcSpec to the top,
to keep clang from reporting a false-positive used-uninitialized problem.

Subject: [PATCH] cmdPoolDiscoverSources: initialize earlier to avoid FP from clang

* tools/virsh.c (cmdPoolDiscoverSources): Always initialize srcSpec.
Otherwise, clang would report that srcSpec could be used uninitialized
in the call to virConnectFindStoragePoolSources.
