cmd: dfu: Add error handling for failed registration
Without this, if g_dnl_register() fails, DFU code continues on blindly and crashes. This fix makes it simply print an error message instead. Signed-off-by: Sanchayan Maity <maitysanchayan@gmail.com> [l.majewski@samsung.com - some manual tweaks needed]
