Hello,

Fixes three issues reported by Luis Chamberlain with one simpler approach:

- race between between zram_reset_device() and disksize_store() (1/4)

- zram leak during unloading module, which is one race between resetting
and removing device (2/4)

- race between zram_remove and disksize_store (3/4)

Also replace replace fsync_bdev with sync_blockdev since no one opens
it.(4/4)

V3:
	- no code change
	- update commit log or comment as Luis suggested
	- add reviewed-by tag

V2:
	- take another approach to avoid failing of zram_remove()
	- add patch to address race between zram_reset_device() and
	  disksize_store()

  zram: fix race between zram_reset_device() and disksize_store()
  zram: don't fail to remove zram during unloading module
  zram: avoid race between zram_remove and disksize_store
  zram: replace fsync_bdev with sync_blockdev

Andrew Morton usually takes zram patches so Ccing him.
