fix minor problem in previous strtod non-nearest rounding bug fix
commit 6ffdc4579ffb34f4aab69ab4c081badabc7c0a9a set lnz in the code path for non-zero digits after a huge string of zeros, but the assignment of dc to lnz truncates if the value of dc does not fit in int; this is possible for some pathologically long inputs, either via strings on 64-bit systems or via scanf-family functions. instead, simply set lnz to match the point at which we add the artificial trailing 1 bit to simulate nonzero digits after a huge run of zeros.
