Subject: [PATCH] ext4: mballoc: avoid garbage value from err
clang warning: fs/ext4/mballoc.c, line 4178, column 6
Branch condition evaluates to a garbage value.
err is uninitialized and will be judged when it enters the
loop first time and the condition "!ext4_sb_block_valid()"
is true. Although this can't make problems now, it's better
to correct it.
