misc: fastrpc: Avoid updating PD type for capability request
When user is requesting for DSP capability, the process pd type is
getting updated to USER_PD which is incorrect as DSP will assume the
process which is making the request is a user PD and this will never
get updated back to the original value. The actual PD type should not
be updated for capability request and it should be serviced by the
respective PD on DSP side. Don't change process's PD type for DSP
capability request.
