USB: gadget: Add 10 microsec delay before fetching setup_data

USB hardware sometimes generate interrupt before 8 bytes of
SETUP packet are written to system memory.
This results in wrong setup_data when tried to read immediately
after receiving an interrupt.
Add a delay of 10 microsec before fetching setup packet to allow
writes from hardware to system memory to complete.
