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.)
