[PATCH] scsi: smartpqi: mark PM functions as __maybe_unused

[Arnd Bergmann <arnd@arndb.de>]

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.

Fixes: f44d210312a6 ("scsi: smartpqi: add suspend and resume support")
