powerpc/vas: Return -EINVAL if the offset is non-zero in mmap()
The user space calls mmap() to map VAS window paste address
and the kernel returns the complete mapped page for each
window. So return -EINVAL if non-zero is passed for offset
parameter to mmap().
See Documentation/arch/powerpc/vas-api.rst for mmap()
restrictions.
