iwlwifi: dnt: make dbgm/log debugfs file continuous
Since the debugfs represents a limited ring buffer,
it makes more sense to use a continuous file (with
block mechanism) rather than using polling.
Using a blocking debugfs mechanism introduce new issues
wrt. op_mode stop (where the relevant data is being
deleted) vs. already opened files. Add additional
waitqueue and counter to synchronize it.
