qcacld-3.0: Enable crash dump for peer delete timeout

Use QDF_BUG to create a crash dump when peer attach operation detects
that the peer already exists even after waiting for 500 ms. It will
detect failure to complete peer delete operation in firmware and
missing peer unmap events.
Crash dump is enabled only when compiled with PANIC_ON_BUG, otherwise
it will print a warning.
