Subject: [PATCH linux] ext4: Delete useless ret assignment

From: luo penghao <luo.penghao@....com.cn>

The assignments in these two places will be overwritten by new
assignments later, so they should be deleted.

The clang_analyzer complains as follows:

fs/ext4/fast_commit.c

Value stored to 'ret' is never read
