ext4: fix on-line resizing regression
https://bugzilla.kernel.org/show_bug.cgi?id=25352 This regression was caused by commit a31437b85: "ext4: use sb_issue_zeroout in setup_new_group_blocks", by accidentally dropping the code which reserved the block group descriptor and inode table blocks. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
