liveupdate fixes for v7.1-rc4

A few fixes for kexec handover and liveupdate:

* make sure KHO is skipped for crash kernel
* fix error reporting in memfd preservation if it fails mid-loop
* don't allow preserving memfds whose page count exceeds UINT_MAX
* fix documentation of memfd seals preservation to match the code
