Revert "kexec: include reserved e820 sections in crash kernel"
This reverts commit e35aa29fb40b37bf86d980b2e19af5e01c2d2549.
This patch is based on the commit 49320340f705694e387d794f7f19d407ad9baefa
"kexec: lengthen the kernel command line image"
Since the latter commit has been reverted due to its useless, this
patch should be reverted too.
Besides, This patch also changed a kernel restriction of max segments
from 16 to 70. Though kexec-tools could have more segments, more than 16,
the kexec_load syscall will still fail for the kernel side has a restriction
of 16.
