Fix data array reset bug
...
io.resp.valid could have been valid the cycle after reset, causing the
write mask in the acquire tracker to have an erroneous value after reset.
This caused the L1 I$ to be refilled with the wrong data.
This probably only affects programs loaded with +loadmem and so shouldn't
matter for the EOS24 silicon. It should only affect the first L2 xact,
which, in practice, would be an HTIF write to load the program.

It still has performance bugs but no correctness bugs AFAIK.
