x86/process: Remove set but not used variables prev and next

Remove two unused variables:

  arch/x86/kernel/process.c: In function ‘__switch_to_xtra’:
  arch/x86/kernel/process.c:618:31: warning: variable ‘next’ set but not used [-Wunused-but-set-variable]
    618 |  struct thread_struct *prev, *next;
        |                               ^~~~
  arch/x86/kernel/process.c:618:24: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable]
    618 |  struct thread_struct *prev, *next;
        |

They are never used and so can be removed.
