ss: mptcp: display info counters as unsigned

Some counters from mptcp_info structure were stored as an unsigned
number (u8) but displayed as a signed one.

Even if it is unlikely these u8 counters -- number of subflows and
ADD_ADDR -- have a value bigger than 2^7, it still sounds better to
display them as unsigned.

Fixes: 9c3be2c0 ("ss: mptcp: add msk diag interface support")
