ext4: fix compile error while opening the macro DOUBLE_CHECK (a2821e34) · Commits · 戴 / test

the error is: fs/ext4/mballoc.c:475:43: error: 'struct ext4_group_info' has no member named 'bb_bitmap'. so, the definition of macro DOUBLE_CHECK should before 'struct ext4_group_info', I fixed it, and I moved the macro AGGRESSIVE_CHECK together, because I think they shoule be together.
