kdump config remove Mellanox eth drivers from ramdisk
This is just an extension of commit:

kdump config remove intel eth drivers from ramdisk
where we removed all of the Intel ethernet drivers
from the kdump ramdisk. They were chewing up scarce
memory and are not needed to dump a vmcore. We should
have also removed the Mellanox network drivers at the
same time. There are some reports of nodes containing
Mellanox cards failing to dump the vmcore after
a kernel crash.
Verification:
- ensure that /etc/kdump.conf now has the omit line
containing the Mellanox drivers
- on plaform containing Mellanox cards, force a
crash dump via echo c >/proc/sysrq-trigger . On the
serial console, watch the crash kernel boot up and
observe that the Mellanox hardware is no longer
initialized by a driver. Watch that the vmcore dump
completes successfully.
