qcacmn: Print the timestamp of FW_HANG command and Tx completion

A customer has reported an issue regarding the FW not asserting when it
receives the WMI_FORCE_FW_HANG_CMDID from the host. We need to confirm
whether the FW actually receiving the command or it is stuck in the WMI
command queue because it’s full.
To do this, adding some prints along with the timestamps in the WMI command
path and WMI command Tx completion path.
