Johannes Berg a8bceb392a iwlwifi: remove per-device debug level
There's no need for the per-device debug
level that we expose in debugfs since the
module parameter is writable in sysfs.

At the same time, simplify code by changing
    iwl_get_debug_level(shrd) & IWL_DL_ISR)
to
    iwl_have_debug_level(IWL_DL_ISR)
