Alejandro Colomar a9e5620c9a kernel: fix off-by-one benign bugs
We were wasting a byte due to an off-by-one bug.  s[c]nprintf() doesn't
write more than $2 bytes including the null byte, so trying to pass
'size-1' there is wasting one byte.

This is essentially the same as the previous commit, in a different
file.
