1. Upon txschq free request, the transmit schedular config in hardware
is not getting reset. This patch adds necessary changes to do the same.

2. Current implementation calls txschq alloc during interface
initialization and in response handler updates the default txschq array.
This creates a problem for htb offload where txsch alloc will be called
for every tc class. This patch addresses the issue by reading txschq
response in mbox caller function instead in the response handler.

3. Current otx2_txschq_stop routine tries to free all txschq nodes
allocated to the interface. This creates a problem for htb offload.
This patch introduces the otx2_txschq_free_one to free txschq in a
given level.

This patch seems to be doing three things.
Could it be split into three patches?

Mainly for my own edification:

	- otx2_mbox_alloc_msg_nix_txsch_free is created via the
	  M(_name, _id, _fn_name, _req_type, _rsp_type) macro
	  around line 844 of  otx2_common.h
	- It calls otx2_mbox_alloc_msg_rsp
	- Which does not call any allocation functions such as kmalloc

I think that given the above it's ok to log an error here.
As the allocation core won't have (because it's not used here.
But I wonder if it would be more consistent with how
allocation errors are usually handled to move the logging into
otx2_mbox_alloc_msg_rsp().

I see that I was a bit late with my review as the
series was applied yesterday.
