   The nxsched_switch_context() function should only be called
   when a task switch actually occurs. The RISC-V architecture
   already performs this call in riscv_perform_syscall(),
   so this PR removed the redundant nxsched_switch_context() call in
   up_switch_context().
   
   
   ## Summary
   
   removed the redundant nxsched_switch_context() call in
   up_switch_context() for arch risc-v
   
   ## Impact
   
   risc-v arch implementation improvement, no impact to other nuttx parts
   
   ## Testing
   
   **ostest passed on board qemu-rv/rv-virt**
