hw/riscv/boot.c: exit early if filename is NULL in load functions
riscv_load_firmware(), riscv_load_initrd() and riscv_load_kernel() works
under the assumption that a 'filename' parameter is always not NULL.
This is currently the case since all callers of these functions are
checking for NULL before calling them. Add an g_assert() to make sure
that a NULL value in these cases are to be considered a bug.
