crypto: caam/qi - Change a couple IS_ERR_OR_NULL() checks to IS_ERR()

Browse Source 
create_caam_req_fq() doesn't return NULL pointers so there is no need to
check.  The NULL checks are problematic because it's hard to say how a
NULL return should be handled, so removing the checks is a nice cleanup.
