drivers/block/null_blk_main.c: fix uninitialized var warnings
With gcc-7.2, many instances of drivers/block/null_blk_main.c: In function ‘nullb_device_zone_nr_conv_store’: drivers/block/null_blk_main.c:291:12: warning: ‘new_value’ may be used uninitialized in this function [-Wmaybe-uninitialized] dev->NAME = new_value; \ ^ drivers/block/null_blk_main.c:279:7: note: ‘new_value’ was declared here TYPE new_value; \ ^ Presumably notabug, so use uninitialized_var() to suppress them.
