wifi: ath9k: use IS_ERR() with debugfs_create_dir()
[ Upstream commit 1e4134610d93271535ecf900a676e1f094e9944c ]
The debugfs_create_dir() function returns error pointers,
it never returns NULL. Most incorrect error checks were fixed,
but the one in ath9k_htc_init_debug() was forgotten.
Fix the remaining error check.
