USB: cypress_m8: Get rid of pointless NULL check
Remove a NULL check in cypress_m8; the check is useless in this context because it is referenced earlier in the same code path thus the kernel would be oops'ed before reaching this point anyway. (And it's really pointless here anyway; if this pointer somehow is NULL the driver is going to have serious problems in many other places.)
