vboot/vboot_kernel: pass VbDiskInfo into LoadKernel

Pass VbDiskInfo struct into LoadKernel, rather than copying all
of its members into LoadKernelParams.  Remove the unused members
from LoadKernelParams.

This CL is part of a series to merge vboot1 and vboot2.0
kernel verification code; see b/181739551.
