From: Wang ShaoBo <bobo.shaobowang@xxxxxxxxxx>
[ Upstream commit 3cded66330591cfd2554a3fd5edca8859ea365a2 ]
Fix to return PTR_ERR() error code from the error handling case where
ubifs_hash_get_desc() failed instead of 0 in ubifs_init_authentication(),
as done elsewhere in this function.
Fixes: 49525e5eecca5 ("ubifs: Add helper functions for authentication support")
