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.

In Genoa SDIO ADMA implementation Host sends packets to FW in
multiples of SDIO Block size.
If the packet/bundle is not block aligned Host adds padding at the
end of Packet/Bundle.
If the TX packet plus padding exceeds one FW TX Buffer, Padding data
will occupy the next FW TX buffer. Same applies for bundle TX packet.
For above scenario, HTC_FLAGS_PADDING_CHECK of HTC header Flags is used
to notify the FW that - Padding data follows the currentHTC packet
Since the padding data will take one extra FW Tx Buffer, host need to
handle the extra Tx credit being used by the padding data/buffer

When polling mode is enabled, send completions for a
CE(host->target, ULpipe) for a particular service(WMI/HTC/HTT) are handled
only when recv happens in CE(target->host, DLpipe) for the same service.
Since for services like WMI there are multiple ULpipes(Eg. CE3 for
WMI<WMAC1> and CE7 for WMI<WMAC2>) and single DLpipe(CE2). Receive on a
DLpipe is the right time to poll for send completions on all ULpipes for
that service.
