spd: tlkd: remove unwanted assert on System Suspend entry

c_rt_ctx is used to store current SP before the system goes
into suspend. The assert for its value being zero is not
really necessary as the value gets over-written eventually.

This patch removes assert(tlk_ctx->c_rt_ctx == 0) from the
System Suspend path, as a result.
