Calling error_get_progname() in the context of qemu-nbd can cause
segmentation fault because qemu-nbd doesn't initialize its progname
with error_set_progname(). This patch adds the initialization.

Currently, the missing call of error_set_progname() doesn't cause any
problems because qemu-nbd doesn't use error_get_progname(). This patch
is a proactive action.
