Peter Maydell e7768429c8 linux-user: make pwrite64/pread64(fd, NULL, 0, offset) return 0 
Linux returns success if pwrite64() or pread64() are called with a
zero length NULL buffer, but QEMU was returning -TARGET_EFAULT.

This is the same bug that we fixed in commit 58cfa6c2e6
for the write syscall, and long before that in 38d840e679
for the read syscall.
