Subject: [PATCH v2 4/7] ext4: use ext4_buffer_uptodate() in __ext4_get_inode_loc()

We have already introduced ext4_buffer_uptodate() to re-set the uptodate
bit on buffer which has been failed to write out to disk. Just remove
the redundant codes and switch to use ext4_buffer_uptodate() in
__ext4_get_inode_loc().
