generic: fix kernel panic on existing mac-address node

Calling free for the OF property can result in a kernel panic, as the
buffer in question might be referenced elsewhere. Also, it is not
removed from the tree.

Always allocate a new property and updating the tree with it fixes both
issues.

Fixes commit 91a52f22a13d ("treewide: backport support for nvmem on non platform devices")
