mmc: cmdq_hci: fix platform device power management reference counting
After issuing a request the usage_count is decremented. After idle time
controller irq is disabled by platform device runtime pm and request
complete irq is not handled.
This change moves decrement of usage_count from the end of issuing request
to the end of request completion.
