UBIFS: unify error path dbg_debugfs_init_fs
UBIFS: unify error path dbg_debugfs_init_fs

This is just a small clean-up patch which simlifies and unifies the
error path in the dbg_debugfs_init_fs(). We have common error path
for all failure cases in this function except of the very first
case. And this patch makes the first failure case use the same
error path as the other cases by using the 'fname' and 'dent'
variables.
