system/physmem: Silence warning from ubsan
When compiling QEMU with --enable-ubsan there is a undefined behavior
warning when running the bios-tables-test for example:
.../system/physmem.c:3243:13: runtime error: applying non-zero offset 262144 to null pointer
#0 0x55ac1df5fbc4 in address_space_write_rom_internal .../system/physmem.c:3243:13
The problem is that buf is indeed NULL if the function is e.g. called
with type == FLUSH_CACHE. Add a check to fix the issue.
