isofs: Fix lseek() to position beyond 4 GB
isofs supports files larger than 4 GB by using multi-extent files.
However an lseek() to a position beyond 4 GB in such a file will
fail with EINVAL, because s_maxbytes in the isofs superblock is
initialized to 2^32-1, and generic_file_llseek() checks against
that value.
I therefore suggest increasing the value of s_maxbytes to have
full support for large files in isofs. With multi-extent files, file
size is only limited by the maximum size of the file system (8 TB),
so this seems a reasonable value for s_maxbytes.
