Subject: [PATCH 4/4] platform/x86: fujitsu-laptop: make hotkey handling functions more similar

Make two minor tweaks to acpi_fujitsu_hotkey_press() to make it more
similar to acpi_fujitsu_hotkey_release():

  * call vdbg_printk() after reporting the input event,
  * return immediately when kfifo_in_locked() fails.
