LOG: [NVPTX] Add unreachable for TMA Inst Printer (#117850)

This patch adds the llvm_reachable() for TMA
reduction opcode printer method, outside the
switch.

We had this inside the default-case leading to
the warning below (and hence was removed):
error: default label in switch which covers all enumeration values
         [-Werror,-Wcovered-switch-default]
