qcacld-3.0: Disable PANIC_ON_BUG for end user builds

PANIC_ON_BUG is currently enabled for all WLAN builds. While a customer
can, and should, disable PANIC_ON_BUG for end user builds, this can be
easily overlooked. Disable PANIC_ON_BUG by default on pure performance
builds, to avoid accidentally crashing end user devices. Customers can
opt-in to PANIC_ON_BUG as needed for validation on performance builds.
