Subject: [PATCH v2] staging: rtl8723bs: ignore unused wiphy_wowlan object warnings

The wake-on-wlan stub is unused when the device power management
functionality is disabled in the kernel, creating a warning when
building the driver.

drivers/staging/rtl8723bs/os_dep/ioctl_cfg80211.c:50:42: warning: =E2=80=
=98wowlan_stub=E2=80=99 defined but not used [-Wunused-const-variable=3D]

Add the __maybe_unused annotation to silence this warning.

Signed-off-by: Bryan Brattlof <hello@bryanbrattlof.com>

Changes from v1:
 - Use the __maybe_unused annotation instead of #ifdef
