Subject: s390/qeth: remove unused code in qdio_establish_cq()
Patch-mainline: v4.15-rc1
Git-commit: 9627923062b6a5c40964b188bb222ec8c02fd2d6
References: FATE#326350, LTC#169511, bsc#1113509

Summary:     qeth: performance improvements
Description: This adds recent functional and performance improvements for the
             qeth network driver.
             Primarily this brings Scatter-Gather support for HiperSockets,
             reduced CPU consumption in the L3 IPv4 transmit path for OSA,
             improved Promiscuous Mode performance due to IFF_UNICAST_FLT,
             support for Scatter-Gather on z/VM virtual NICs, and
             support for delayed GRO flushing.

             For sanity & stability reasons, this effectively constitutes a
             backport of the qeth device driver from 4.19 mainline.

             s390/qeth: remove unused code in qdio_establish_cq()

             Storing the number of input buffers into 'i' has no effect, it is
             immediately re-assigned in the next line.
