The ie_len field in struct mesh_setup stores the length of the
information elements (IEs) buffer. It is currently defined as u8,
which limits the maximum supported length to 255 bytes.

The IE length is derived from memory buffers whose size is naturally
represented by size_t. Using u8 may truncate larger values and can
result in incorrect length handling.

Change ie_len to size_t so it can represent the full buffer length and
match the type commonly used for memory sizes throughout the kernel.
