block/raw-posix: Use raw_normalize_devicepath()
The filename given to qemu_open() in block/raw-posix.c should generally have been processed by raw_normalize_devicepath(); unless we are only probing (in which case the caller often checks whether the file is a block device or not, and this property will be changed by raw_normalize_devicepath() on NetBSD) or it is about a deprecated device (i.e. floppy).
