cxgb4: Fix static checker warning
The patch e85c9a7abf
: ("cxgb4/cxgb4vf: Add code to calculate T5 BAR2
Offsets for SGE Queue Registers") from Dec 3, 2014, leads to the
following static checker warning:
drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:5358
t4_bar2_sge_qregs()
warn: should '(qid >> qpp_shift) << page_shift' be a 64 bit type?
This patch fixes it
