Revert "staging: zram: Add auto loading of module if user opens /dev/zram."

This reverts commit c70bda992c12e593e411c02a52e4bd6985407539.

It's incorrect, Kay writes:
	Please just remove it. "devname" is meant to be used for
	single-instance devices with a static dev_t, never for things
	like zramX.

	It will not do anything useful here, it does nothing really
	without a statically assigned dev_t, and it should not be used
	for devices of this kind anyway.

Staging: zram: Fix access of NULL pointer

commit 46a51c80216cb891f271ad021f59009f34677499 upstream.

This patch fixes the bug in reset_store caused by accessing NULL pointer.

The bdev gets its value from bdget_disk() which could fail when memory
pressure is severe and hence can return NULL because allocation of
inode in bdget could fail.

Hence, this patch introduces a check for bdev to prevent reference to a
NULL pointer in the later part of the code. It also removes unnecessary
check of bdev for fsync_bdev().

Staging: zram: Fix memory leak by refcount mismatch

commit 1b672224d128ec2570eb37572ff803cfe452b4f7 upstream.

As suggested by Minchan Kim and Jerome Marchand "The code in reset_store
get the block device (bdget_disk()) but it does not put it (bdput()) when
it's done using it. The usage count is therefore incremented but never
decremented."

This patch also puts bdput() for all error cases.
