misc: fastrpc: Move fdlist to invoke context structure
The fdlist is currently part of the meta buffer which is set during
fastrpc_get_args(), this fdlist is getting recalculated during
fastrpc_put_args().
Move fdlist to the invoke context structure to improve maintainability
and reduce redundancy. This centralizes its handling and simplifies
meta buffer preparation and reading logic.
