Rakesh Pillai 4863352e53 qcacmn: Unmap the htc connect buffer after connect failure ...

The htc connect message buffer is not unmapped,
if the firmware does not send wmi ready event to the
host.

Scenario:
- Host sends htc init command.
- The command is queued into the src ring.
- The firmware has crashed before the Copy Engine
  could copy the message to the destination ring
- Due to the above point, no copy completion
  interrupt is received.
- The host times out during its wait for the wmi
  ready event.
- Hence the htc init command buffer stays unmapped
  and unfreed.

As a part of the wma ready event missing cleanup,
the htc connect buffer is not unmapped. Fix this
to avoid missing to unmap the buffer.

To avoid a side effect of sending a completion for
HTC connect command, all the commands are freed in
the htc completion handler in case of SSR.
