md: bcache: avoid -Wempty-body warnings
building with 'make W=1' shows a harmless warning for each user of the EBUG_ON() macro: drivers/md/bcache/bset.c: In function 'bch_btree_sort_partial': drivers/md/bcache/util.h:30:55: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body] 30 | #define EBUG_ON(cond) do { if (cond); } while (0) | ^ drivers/md/bcache/bset.c:1312:9: note: in expansion of macro 'EBUG_ON' 1312 | EBUG_ON(oldsize >= 0 && bch_count_data(b) != oldsize); | ^~~~~~~ Reword the macro slightly to avoid the warning.
