Subject: [PATCH][rdma-next] RDMA/hns: remove redundant assignment to variable j

From: Colin Ian King <colin.king@...onical.com>

Variable j is being assigned to loop_j and then later being
assigned to a new value in for loops. The first initialization
is therefore redundant and can be removed.

Cleans up clang warning:
warning: Value stored to 'j' is never read
