ext4: add correct group descriptors and reserved GDT blocks to system zone

Browse source

commit 68228da51c upstream.

When setup_system_zone, flex_bg is not initialized so it is always 1.
Use a new helper function, ext4_num_base_meta_blocks() which does not
depend on sbi->s_log_groups_per_flex being initialized.

[ Squashed two patches in the Link URL's below together into a single
  commit, which is simpler to review/understand.  Also fix checkpatch
  warnings. --TYT ]
