starfive: avoid NULL dereference in fdt_check_header()

Browse Source 
If the u-boot.itb read from SD-card is invalid, fdt_check_header() may be
called with a NULL pointer.

This was observed on an StarFive VisionFive Lite when trying to revover the
board via UART.

Add a missing check in the starfive board code.
