Subject: [PATCH v2 6/7] ext4: remove unneeded NULL check of buffer_head in ext4_mark_inode_used()

If gdp from ext4_get_group_desc() is not NULL, then returned group_desc_bh
won't be NULL either. Remove check of group_desc_bh and only check
returned gdp from ext4_get_group_desc() like how other callers do.
