Fix a couple warnings that pop when building with rpmbuild:

builtin-zero-labels.c: In function 'cmd_zero_labels':
builtin-zero-labels.c:50:20: warning: 'err' may be used uninitialized in this function [-Wmaybe-uninitialized]
lib/libndctl.c: In function 'ndctl_bind':
lib/libndctl.c:3073:5: warning: 'rc' may be used uninitialized in this function [-Wmaybe-unini
