LU-11579 llite: remove cl_file_inode_init() LASSERT

If there is some corruption or other reason that the file layout
cannot be used, the first call to cl_file_inode_init() will fail.
If it is called a second time on the same file then it will hit
an LASSERT() since I_NEW is no longer set on the inode.

It would be good to handle the error in lov_init_raid0() better,
but we still want to avoid this LASSERT() if there is an error.

Convert the LASSERT() in cl_file_inode_init() into a CERROR() and
error return.  This is being triggered due to corruption on the
server, but that shouldn't cause the client to assert.

Instead, return an IO error instead of killing the client.
