Wachowski, Karol b039f1c4d3 accel/ivpu: Correct MMU queue size checking functions 
Do not use kernel CIRC_SPACE and CIRC_CNT that
incorrectly return space of a queue when wrap bit was set.
Use correct implementation that compares producer, consumer and
wrap bit values.

Without this fix it was possible to lose events in case when event
queue was full.
