UBIFS: fix error path in dbg_debugfs_init_fs
The debug interface is substandard and on error returns either
NULL or an error code packed in the pointer. So using "IS_ERR"
for the pointers returned by debugfs function is incorrect.
Instead, we should use IS_ERR_OR_NULL.
This path is an improved vestion of the original patch from
Phil Carmody.
