Now if either glfs_set_volfile_server() or glfs_set_logging() fails, we end up doing glfs_fini() which eventually hangs in glfs_lock().

Note that we haven't done glfs_init() in this failure case.
- Is this failure expected ? If so, what is the recommended way of releasing the glfs object ?
- Does glfs_fini() depend on glfs_init() to have worked successfully ?
- Since QEMU-GlusterFS driver was developed when libgfapi was very new, can gluster developers take a look at the order of the glfs_* calls we are making in QEMU and suggest any changes, improvements or additions now given that libgfapi has seen a lot of development ?
