3.16.37-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit 5b4d10f5e0369ed79434593b7cd8e85eebbe473f upstream.

There is a static checker warning here "warn: mask and shift to zero"
and the code sets "ring" to zero every time.  From looking at how
QLCNIC_FETCH_RING_ID() is used in qlcnic_83xx_process_rcv_ring() the
qlcnic_83xx_hndl() should be removed.

Fixes: 4be41e92f7c6 ('qlcnic: 83xx data path routines')
