qcacld-3.0: Fix assert in wma_rx_service_ready_ext_event API

Browse source 
In case of legacy/old platform, extended caps are not provided and
number of supported hw modes is expected to come as zero. Due to
bug in a code, driver is going ahead and try to allocated memory
with size of 0 bytes which is causing the assert.
