fix regression in ioctl definitions provided by arch/generic bits

commit b60fdf133c033d4ad6b04a8237f253563fae5928 broke the
SIOCGSTAMP[NS] ioctl fallbacks introduced in commit
2e554617e5a6a41bf3f6c6306c753cd53abf728c, as well as use of these
ioctls, by creating a situation where bits/ioctl.h could be included
without __LONG_MAX being visible.
