ext4: fix kernel oops caused by spurious casefold flag If an directory has the a casefold flag set without the casefold feature set, s_encoding will not be initialized, and this will cause the kernel to dereference a NULL pointer. In addition to adding checks to avoid these kernel oops, attempts to load inodes with the casefold flag when the casefold feature is not enable will cause the file system to be declared corrupted.
