Subject: kexec: Fix option checks to take KEXEC_FILE_LOAD into account
References: bsc#1080916, boo#1076839
Upstream: merged
Git-commit: bf36a4623b5ef67b3ae9722972fc135c608df963

When kexec_file_load support was added some sanity checks were not updated.

Some options are set only in the kexec_load flags so cannot be supported
wiht kexec_file_load. On the other hand, reserved memory is needed for
kdump with both kexec_load and kexec_file_load.
