pci/dmar: correct off-by-one error in dmar_fault() DMAR faults are recorded into a ring of "fault recording registers". fault_index is a 0-based index into the ring. The code allows the 0-based fault_index to be equal to the total number of fault registers available from the cap_num_fault_regs() macro, which causes access beyond the last available register.
