Dongyan Qian 5db0091418 UefiCpuPkg/ExceptionHandler: Fix a context error in LoongArch64
On the LoongArch platform:
 the a0 register can be used as both a function parameter and a return value.

Due to parameter EFI_SYSTEM_CONTEXT being overwritten by an invalid context address,
when calling GetExceptionType, incorrect parameter address causes memory access exception.
