hpet: remove useless check if fixmem32 is NULL
fixmem32 is assigned to address of res->data member
so the address is always valid
Actually since we are not checking for res != NULL
static analyzing is complaining about referencing the pointer
and consequent check for null.
The code snippet looks confusing also for human eyes.
