qcacld-3.0: Donot de-init DP RX threads if not inited

In one of the tests, when the driver switches to FTM mode, DP RX threads
are not initialized as the necessary configuration is not passed down
from CDS. However, cds_dp_close tries to de-initialize the threads and a
spinlock un-initialized error is seen.

Donot de-initialize the DP RX thread module if it is not initialized.
