Dan Carpenter 7504fb57af ext4: fix potential unnitialized variable 
[ Upstream commit 3f4830abd2 ]

Smatch complains "err" can be uninitialized in the caller.

    fs/ext4/indirect.c:349 ext4_alloc_branch()
    error: uninitialized symbol 'err'.

Set the error to zero on the success path.

Fixes: 8016e29f43 ("ext4: fast commit recovery path")
