In some cases device sending ZLP IN on non EP0 which
reassigning EP0 OUT descriptor pointer to that EP.
Dedicated for EP0 OUT descriptor multiple time re-used by
other EP while that descriptor already in use by EP0 OUT
for SETUP transaction. As result when SETUP packet received
BNA interrupt asserting.

In dwc2_hsotg_program_zlp() function dwc2_gadget_set_ep0_desc_chain()
must be called only for EP0.
