KVM: s390: rename PROT_NONE to PROT_TYPE_DUMMY

The enum type prot_type declared in arch/s390/kvm/gaccess.c declares an
unfortunate identifier within it - PROT_NONE.

This clashes with the protection bit define from the uapi for mmap()
declared in include/uapi/asm-generic/mman-common.h, which is indeed what
those casually reading this code would assume this to refer to.

This means that any changes which subsequently alter headers in any way
which results in the uapi header being imported here will cause build
errors.

Resolve the issue by renaming PROT_NONE to PROT_TYPE_DUMMY.
