qcacld-3.0: Retry sending packets in htc queue

A race condition is observed when runtime suspend is aborted
due to pending TX packets but context switch happened and pm_state
did not revert to active state yet. In parallel, WMI_PEER_DELETE
command is queued but not sent as pm_state is still in suspending
state.
To fix this, schedule HTC queue kicker work to resend pending
commands again after dp_runtime_suspend aborts due
to pending TX packets.
