erofs: update erofs_inode_is_data_compressed helper

Browse source

As Christoph said, "This looks like a really obsfucated
way to write:
	return datamode == EROFS_INODE_FLAT_COMPRESSION ||
		datamode == EROFS_INODE_FLAT_COMPRESSION_LEGACY; "

Although I had my own consideration, it's the right way for now.
