Subject: [PATCH] ubifs: journal: Fix error return code in
 ubifs_jnl_write_inode()

[ Upstream commit a2c2a622d41168f9fea2aa3f76b9fbaa88531aac ]

Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.

Fixes: 9ca2d7326444 ("ubifs: Limit number of xattrs per inode")
