[PATCH] ext3: Properly report backup block present in a group

In filesystems with the meta block group flag on, ext3_bg_num_gdb() fails
to report the correct number of blocks used to store the group descriptor
backups in a given group.  It happens because meta_bg follows a different
logic from the original ext3 backup placement in groups multiples of 3, 5
and 7.
