staging: ramster: delete the driver 



Turns out it's not quite ready to be included, thanks to some other work
done in the zcache and zram code, which breaks this driver.

So, delete it for now, per the recommendation of Dan.

	  RAMster allows RAM on other machines in a cluster to be utilized

	  dynamically and symmetrically instead of swapping to a local swap

	  disk, thus improving performance on memory-constrained workloads

	  while minimizing total RAM across the cluster.  RAMster, like

	  zcache, compresses swap pages into local RAM, but then remotifies

	  the compressed pages to another node in the RAMster cluster.

For this staging driver, RAMster duplicates code from fs/ocfs2/cluster

and from drivers/staging/zcache, then incorporates changes to the local

copy of the code.  Before RAMster can be promoted from staging, this code

duplication must be resolved.  Specifically, we will first need to work with

the ocfs2 maintainers to split out the ocfs2 core cluster code so that

it can be easily included by another subsystem, even if ocfs2 is not

configured, and also to merge the handful of functional changes required.

Second, the zcache and RAMster drivers should be either merged or reorganized

to separate out common code.
