[Crash-utility] [PATCH 1/6] LoongArch64: print exception return address as ERA

LoongArch saves the exception return address in CSR.ERA. The crash LoongArch64 code currently labels this field as EPC in register and exception-frame output. That is misleading when comparing crash output with the architecture documentation and the kernel pt_regs layout. Rename the displayed field to ERA and fix the CSR.EUEN label while updating the same output block. This is a display-only change and does not alter how the saved exception return address is collected or used by the unwinder.
