ext4: Don't allow new groups to be added during block allocation
(cherry picked from commit 8556e8f3b6c4c11601ce1e9ea8090a6d8bd5daae)
After we mark the blocks in the buddy cache as allocated,
we need to ensure that we don't reinit the buddy cache until
the block bitmap is updated. This commit achieves this by holding
the group_info alloc_semaphore till ext4_mb_release_context
