C2H on rtwn not handled

[Farhan Khan]

Hi Andriy,

Just to be clear, this would mean that in my sc_post_init, I should not 
utilize callout_reset, which utilizes r92c_handle_c2h_report, correct? 
This appears to be how rtl

If so, how do I know when a C2H event arrives? (I am not too familiar 
with C2H or how it works yet).

As always, thank you very much.
