qcacld-3.0: Do not allow suspend during roaming

Browse Source 
There is a chance that kernel can trigger suspend while reassoc
in progress. If driver allows this suspend, this can result in
two issues:
1. Authentication timeout in supplicant and leads to connection
   failure if reassoc is triggered using reassoc bssid hint.
2. Roam synch timeout in firmware if roaming is triggered from fw.

Add one more check for roaming in progress to fix this issue.
