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

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
