qcacld-3.0: Use hdd_for_each_sta_ref_safe API for connection status

When a NAN request(NAN enable/disable/any generic) is received
from userspace, host driver checks if any connection(STA/SAP/P2P)
is in progress by iterating through adapters. The request would be
rejected if any adapter has connection_in_progress status.

But if the adapter is getting cleaned up in parallel while
iterating through the list for connection status, the iterator
callback may stuck in loop. So, use hdd_for_each_sta_ref_safe()
API to avoid stuck in loop.
