fix compile warning and use zd for ssize_t by Randy's suggestion.

drivers/block/zram/zram_drv.c: In function 'read_block_state':
drivers/block/zram/zram_drv.c:674:16: warning: format '%llu' expects argument of type 'long long unsigned int', but argument 5 has type '__kernel_time_t {aka long int}' [-Wformat=]
