powerpc/ptrace: Fix build error in pkey_get()

The merge resolution in commit 25d8d4eecace left ret no longer used,
leading to:

  arch/powerpc/kernel/ptrace/ptrace-view.c: In function ‘pkey_get’:
  arch/powerpc/kernel/ptrace/ptrace-view.c:473:6: error: unused variable ‘ret’
    473 |  int ret;

Fix it by removing ret.
