Subject: [PATCH linux-next] ext4: Remove redundant 'offset' assignment

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

Although it is in the loop, offset is reassigned at the beginning of the
while loop. And know that the function ends, the value will not be used

The clang_analyzer complains as follows:

fs/ext4/dir.c:306:3 warning:

Value stored to 'offset' is never read
