net: bcm4358: fix not to check same value in macro

When BCMBUSTYPE is not defined, then BUSTYPE(bustype) is just
bustype. So comparing bustype and BUSTYPE(bustype) is not necessary.

This patch removes following build warning with gcc 6.
   drivers/net/wireless/bcmdhd4358/siutils.c: In function 'si_doattach':
   drivers/net/wireless/bcmdhd4358/siutils.c:512:14: warning: self-comparison always evaluates to false [-Wtautological-compare]
     if (bustype != BUSTYPE(bustype)) {
                 ^~
