ext4: Fix kernel BUG at fs/ext4/mballoc.c:910!
With the flex_bg feature enabled, a large file creation oopses the
kernel. The BUG_ON is:
BUG_ON(len >= EXT4_BLOCKS_PER_GROUP(sb));
As the allocation of the bitmaps and the inode table can be done
outside the block group with flex_bg, this allows to allocate up to
EXT4_BLOCKS_PER_GROUP blocks in a group.
This patch fixes the oops.
