[HUST CSE] Fix nullptr issue in bsp/rv32m1_vega/ri5cy/board/fsl_host.c (#7236)
During the process of statically checking the source code, it was found that this judgment directly obtained the member of the structure pointer without performing a null pointer check. When an upstream function has an exception and passes in a null pointer, a runtime error will occur.
