[PATCH 1/2] staging: ramster: build ramster properly when CONFIG_OCFS2=m|y

[Dan Magenheimer]

Due to some conflicting debug vars, kernel build will warn when
CONFIG_RAMSTER=y and CONFIG_OCFS2=m and will fail when
CONFIG_RAMSTER=y and CONFIG_OCFS2=y (rare).

Rename ramster mlog vars to avoid the name conflict.
