fs: cbfs: remove wrong header validation
cbfs_fileheader.len indicates the content size of the file in the
cbfs, and it has nothing to do with cbfs_fileheader.offset which
is the starting address of the file in the cbfs.
Remove such check in file_cbfs_next_file(). Before this change
'cbfsinit' failed with 'Bad CBFS file'. After this change all cbfs
commands are working as expected.
