[Rahul Lakkireddy <rahul.lakkireddy@chelsio.com>]

Fix following build errors reported by Intel C++ compiler in Windows
build.

C:\> t4_hw.c(5105): warning #147: declaration is incompatible with
"int t4_bar2_sge_qregs(struct adapter *, unsigned int, unsigned int,
u64={uint64_t={unsigned __int64}} *, unsigned int *)"
(declared at line 524 of "..\..\..\..\drivers\net\cxgbe\base\common.h")
    int t4_bar2_sge_qregs(struct adapter *adapter, unsigned int qid,
        ^

        n_user_filters = mult_frac(adap->tids.nftids,
                         ^

C:\> sge.c(400): error : expression must be a pointer to a complete
object type
