An assigned value that is never used may represent unnecessary computation,
an incorrect algorithm, or possibly the need for cleanup or refactoring.

In reassemble_packets: A value assigned to a variable is never used.

Fixes: cf4b4708a88a ("ixgbe: improve slow-path perf with vector scattered Rx")
Coverity ID 13335

Fix now needs to be applied to ixgbe_rxtx_vec_common.h since the ixgbe vector
rework, but since it's only a one-line change it's easy enough to fix on apply.
