scsi: smartpqi: mark PM functions as __maybe_unused 

The newly added suspend/resume support causes harmless warnings when
CONFIG_PM is disabled:

smartpqi/smartpqi_init.c:5147:12: error: 'pqi_ctrl_wait_for_pending_io' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2019:13: error: 'pqi_wait_until_lun_reset_finished' defined but not used [-Werror=unused-function]
smartpqi/smartpqi_init.c:2013:13: error: 'pqi_wait_until_scan_finished' defined but not used [-Werror=unused-function]

We can avoid the warnings by removing the #ifdef around the handlers and
instead marking them as __maybe_unused, which will let gcc drop the
unused code silently.
