[PATCH 5.4 280/453] ubifs: Fix error return code in ubifs_init_authentication()

[Greg Kroah-Hartman]

From: Wang ShaoBo <bobo.shaobow...@huawei.com>

[ 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")
