net: nixge: Fix error path for obtaining mac address
Fix issue where nixge_get_nvmem_address() returns a non-NULL return value on a failed nvmem_cell_get() that causes an invalid access when error value encoded in pointer is dereferenced. Furthermore ensure that buffer allocated by nvmem_cell_read() actually gets kfreed() if the function succeeds.
