s390/vmlogrdr: change return value from -ENOSYS to -EOPNOTSUPP

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Changing the return value of vmlogrdr_open() to -EOPNOTSUPP if O_NONBLOCK
is specified shouldn't have any negative side effects.
Any existing user wouldn't specify that flag since it wouldn't work anyway.
