[netdrvr tulip] fix hashed setup frame code

It is using local variable `i' in both the inner and outer loop.

Need to bring the for loop outside the loop.  Otherwise we need to reset the
setup_frame to tp->setup_frame after every loop.  You do not need to set the
setup_frm for every mc address, we can set once after the complete has_table
is ready.
