Subject: io.c (NUM2IOCTLREQ): Accept a value more than INT_MAX

ioctl accepts int as request arguments on some platforms, but some
requests are more than INT_MAX, e.g., RNDGETENTCNT(0x80045200).
Passing (0x80045200 | (-1 << 32)) may work around the issue, but it may
not work on a platform where ioctl accepts unsigned long.  So this
change uses NUM2LONG and then casts it to int.
