According to the documentation in memory.h a ROM memory region will be backed by RAM for reads, but is supposed to go through a callback for writes. Currently we were not checking for the existence of the rom_device flag when determining if we could perform a direct write or not. To correct that add a check to memory_region_is_direct so that if the memory region has the rom_device flag set we will return false for all checks where is_write is set.
