[PATCH] ramoops: make it possible to change mem_type param.

[Wang Long <long.wanglong@huawei.com>]

If we set ramoops.mem_type=1 in command line, the current
code can not change mem_type to 1, because it is assigned
to 0 in function ramoops_register_dummy.

This patch make it possible to change mem_type parameter
in command line.
