fs/minix: set s_maxbytes correctly
The minix filesystem leaves super_block::s_maxbytes at MAX_NON_LFS rather than setting it to the actual filesystem-specific limit. This is broken because it means userspace doesn't see the standard behavior like getting EFBIG and SIGXFSZ when exceeding the maximum file size. Fix this by setting s_maxbytes correctly.
