[ Upstream commit 38b16d6cfe ]
As the potential failure of the allocation, kmemdup() may return NULL.
Then, 'bin_attr_data_vault.private' will be NULL, but
'bin_attr_data_vault.size' is not 0, which is not consistent.
Therefore, it is better to check the return value of kmemdup() to
avoid the confusion.
