frv: kill used but uninitialized variable

Commit 6afe1a1fe8ff ("PM: Remove legacy PM") removed the initialization
of retval, causing:

  arch/frv/kernel/pm.c: In function 'sysctl_pm_do_suspend':
  arch/frv/kernel/pm.c:165:5: warning: 'retval' may be used uninitialized in this function [-Wuninitialized]

Remove the variable completely to fix this, and convert to a proper
switch (...) { ... } construct to improve readability.
