[PATCH linux] nfs: Remove unnecessary ret assignment

[cgel . zte]

From: luo penghao <luo.penghao@xxxxxxxxxx>

Subsequent if judgments will assign new values to ret, so the
statement here should be deleted

The clang_analyzer complains as follows:

fs/nfs/callback.c:

Value stored to 'ret' is never read
