[PATCH 1/2] zram: forbid IO operations from within zram_init_device()

zram: forbid IO operations from within zram_init_device() Allocation operations in zram_make_request() -> zram_init_device() should not raise IO and nested zram_make_request() -> zram_init_device() from IRQ context, thus we must use GFP_NOIO flag. ===
