ext4: remove unnecessary check in ext4_bg_num_gdb_nometa

We only call ext4_bg_num_gdb_nometa if there is no meta_bg feature or group
does not reach first_meta_bg, so group must not reside in meta group. Then
group has a global gdt if superblock exists. Just remove confusing branch
that meta_bg feature exists.
