f74576cb84 qcacmn: Add TX credits after WMI logging
While processing a host-to-target credit report, the number of available
credits is incremented before recording the credit report event in the
WMI history log. This can lead to tricky debug scenarios where there is
an available credit, but the WMI history log does not show that a credit
report has been processed. In htc_process_credit_rpt, log the credit
report in the WMI history log before incrementing the available credits
field.

bc9718fea2 qcacmn: Fix HTC packet map/unmap disparity
When a data packet is sent via HTC, it is mapped before being inserted
into the TX queue. However, for control packets, the mapping is done
after being inserted into the queue. This leads to a situation where the
TX queue flush can unmap a pending control packet that was never mapped.
Make sure the TX flush function only unmaps packets that have previously
been mapped.

bbba9176f8 qcacmn: Set the initial wake flag on MSI resume
When the wlan driver is suspending, the last thing it does is check to
see if the firmware has indicated a wakeup during the suspend process.
This is done by checking the initial wakeup flag, which is set when a
specific copy engine payload is received from firmware. For the new
dedicated wake MSI, only the wake signal is received, no payload. When
the wake MSI is toggled, set the initial wakeup flag to prevent race
conditions during the suspend process.

Tx lookup queue holds the reference of the packet that is successfully

One context can get the packet reference in its local lookup Queue and the
other context may not find the reference as this is not brought back
from lookupQueue to TxLookupQueue.

Fix this by adding a per endpoint lookup queue lock.
