Some targets, QCA6390 for example, use only one TCL ring,
it is better to initialize only one ring and leave others
untouched for such targets.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1

It's better? Please be more specific. Does this fix a bug or is this
just a theoretical fix you found during code review?
