qcacld-3.0: Add a wrapper for WIPHY_FLAG_SUPPORTS_SCHED_SCAN

WIPHY_FLAG_SUPPORTS_SCHED_SCAN is removed in Linux kernel versions 4.12+
in favor of proper multiple scheduled scan support. Add conditional
compilation to set the appropriate wiphy state based on which kernel
version is being compiled against.
