HID: playstation: Silence sparse warnings for locking context imbalances

It seems sparse has some difficulties with guard() handling or when
mixing it with scoped_guard(), as it shows a bunch lock related
warnings:

  hid-playstation.c:1230:32: warning: context imbalance in 'dualsense_player_led_set_brightness' - wrong count at exit
  hid-playstation.c:1414:12: warning: context imbalance in 'dualsense_parse_report' - wrong count at exit
  hid-playstation.c:1615:12: warning: context imbalance in 'dualsense_play_effect' - different lock contexts for basic block
  hid-playstation.c:1668:13: warning: context imbalance in 'dualsense_set_lightbar' - wrong count at exit
  hid-playstation.c:1680:13: warning: context imbalance in 'dualsense_set_player_leds' - wrong count at exit
  hid-playstation.c:2185:33: warning: context imbalance in 'dualshock4_led_set_blink' - wrong count at exit
  hid-playstation.c:2226:33: warning: context imbalance in 'dualshock4_led_set_brightness' - wrong count at exit
  hid-playstation.c:2596:12: warning: context imbalance in 'dualshock4_play_effect' - different lock contexts for basic block
  hid-playstation.c:2634:13: warning: context imbalance in 'dualshock4_set_bt_poll_interval' - wrong count at exit
  hid-playstation.c:2642:13: warning: context imbalance in 'dualshock4_set_default_lightbar_colors' - wrong count at exit

Silent them by switching from guard() to scoped_guard() in
{dualsense|dualshock4}_schedule_work().
