bnx2x: fix build when BNX2X_SRIOV is not enabled

Fix build when BNX2X_SRIOV is not enabled.
Change one parameter struct from bnx2 to bnx2x and don't return a value
from a void function.

drivers/net/ethernet/broadcom/bnx2x/bnx2x_sriov.h:576:48: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default]
