nbd/trivial: fix type cast for ioctl
This fixes ioctl behavior on powerpc e6500 platforms with 64bit kernel and 32bit userspace. The current type cast has no effect there and the value passed to the kernel is still 0. Probably an issue related to the compiler, since I'm assuming the same configuration works on a similar setup on x86. Also ensure consistency with previous type cast in TRACE message.
