[dpdk-dev] [PATCH 2/3] net/cxgbe: remove unused variable usage

[Emmanuel Roullit <emmanuel.roullit@gmail.com>]

Found with clang static analysis:
drivers/net/cxgbe/sge.c:900:3: warning:
Value stored to 'in_use' is never read
        in_use += q->size;
        ^         ~~~~~~~

Fixes: c167acb61278 ("net/cxgbe: use I/O device memory read/write API")
