globalvar: fix crash if CONFIG_NVVAR is not set
At the moment globalvar code tries to use nv_device
even if nv_device is not registered.
How to reproduce the problem:
barebox$ make sandbox_defconfig
...
barebox$ sed -i "s/\(CONFIG_NVVAR\)=y/# \1 is not set/" .config
barebox$ sed -i "s/\(CONFIG_DEFAULT_ENVIRONMENT_GENERIC_NEW\)=y/# \1 is not set\n# CONFIG_DEFAULT_ENVIRONMENT_GENERIC is not set/" .config
barebox$ make oldconfig
...
barebox$ make
...
barebox$ ./barebox
Segmentation fault
This patch blocks nv_device use if CONFIG_NVVAR is not set.
