mmc: cmdq: trigger get queue status after dcmd

CMDQ spec defines periodic SEND_STATUS mechanism to poll
on READY tasks in the device. When DAT lines are in IDLE
the counter counts from its reset value to '0' and then
triggers SEND_STATUS command. When CMD13 is completed and
also the syncing of the device status to HCLK domain is done
there is a 1 cycle pulse to reload the counter with timer
reset value so that the counting can start over.

In rare cases, when the 'done' pulse for reloading the
counter happens in parallel to a BUSY state of direct
command - the IDLE counter is not reloaded and can't
trigger another CMD13. If this scenario happens when
there are pending tasks which are not 'READY' yet  - it
can lead to a deadlock, since there is no other mechainsm to
send CMD13, and CQE will never get READY on the pending tasks.

Hence, trigger a send status command after DCMD is completed
as a work-around to the above issue.
