Changes in V5
* Setting and resetting of twt_enabled in WMI functions
* ath11k_dbg() instead of ath11k_info() in ath11k_wmi_twt_add_dialog_event()
* Made WMI error messages more readable

all in one line).

You are not checking that status array is not used out of bounds. I
would just remove the string conversion to keep things simple, but if
you want to print in strings please add a helper function to do the
conversion and add status values as enum to wmi.h.
