ext4: fix block validity checks for journal inodes using indirect blocks
Commit 345c0dbf3a30 ("ext4: protect journal inode's blocks using
block_validity") failed to add an exception for the journal inode in
ext4_check_blockref(), which is the function used by ext4_get_branch()
for indirect blocks. This caused attempts to read from the ext3-style
journals to fail with:
[ 848.968550] EXT4-fs error (device sdb7): ext4_get_branch:171: inode #8: block 30343695: comm jbd2/sdb7-8: invalid block
Fix this by adding the missing exception check.
Fixes: 345c0dbf3a30 ("ext4: protect journal inode's blocks using block_validity")
