Subject: [PATCH v2] ath10k: skip the wait for completion to recovery in shutdown path

Currently in the shutdown callback we wait for recovery to complete
before freeing up the resources. This can lead to unwanted delay
during the shutdown and thereby increase the shutdown time.

As an attempt to take less time during shutdown, remove the wait for
recovery completion in the shutdown callback.

Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1
