mesh_setup::ie_len is currently declared as u8, limiting the maximum
IE length to 255 bytes. Callers may provide larger IE buffers, causing
the length to be truncated and resulting in incomplete or incorrect
processing of mesh information elements.

Use size_t for ie_len to correctly represent the buffer size and align
the field with the kernel's convention for memory lengths.
