rtw88: debug: Fix uninitialized memory in debugfs code

Browse source 
commit 74a8c816fa8fa7862df870660e9821abb56649fe upstream.

This code does not ensure that the whole buffer is initialized and none
of the callers check for errors so potentially none of the buffer is
initialized.  Add a memset to eliminate this bug.
