[LTP] [PATCH] [COMMITTED] include/SAFE_IOCTL() fix return value type

[Cyril Hrubis]

This adds the same trick we use for SAFE_FCNTL() to SAFE_IOCTL(), the
added coma + zero forces the return value to be numeric in all cases so
that compiler will work fine in cases that we want to store the
resulting value from SAFE_IOCTL().
