qcacld-3.0: Host roam failed when need hw mode change

Browse source 
On Genoa, when 2G SAP exist, when STA roam from 2G to 5G by LFR2,
hardware mode need switch from single MAC mode to dbs mode.
Since disconnect current AP happens before reassociate, in
hw mode response handler, found original AP disconnected
already on host side, then don't reassoc new AP, it's regression
of Change-Id: I794c6bf3f749bba9c339fd18b5202d50091b73a7.

Fix: In hw mode response handler, don't check connect state of
current AP when reassoc new AP.
If found disconnect pending during host roaming, don't reassoc.

Add debug log when error happens.
