zram: only make zram_wb_devops for CONFIG_ZRAM_WRITEBACK

If writeback isn't configured, then we get the following warning when
compiling zram:

drivers/block/zram/zram_drv.c:1824:45: warning: unused variable 'zram_wb_devops' [-Wunused-const-variable]

Make sure we only define the block_device_operations if that option is
enabled.
