arch/xtensa: "NMILEVEL" is an optional feature

Some oddballs cores can be generated without an "NMI" interrupt, in
which case core-isa.h will not define XCHAL_NMILEVEL.  This code is
trying to unconditionally mask interrupts, so XCHAL_EXCM_LEVEL is the
pedantically correct choice anyway (NMI's by definition, cannot be
masked).
