i2c: mxs: only flag completion when queue is completely done
commit 844990daa2e69a4258049ba9c2bae1180657dac3 upstream.
The hardware generates an interrupt for every completed command in the
queue while the code assumed that it will only generate one interrupt
when the queue is empty. So, explicitly check if the queue is really
empty. This patch fixed problems which occurred due to high traffic on
the bus. While we are here, move the completion-initialization after the
parameter error checking.
