Updated the git commit as follows and applied to

eventdev/crypto: fix enqueueing invalid ops
When tail pointer of circular buffer rolls over as the circular buffer
becomes full, crypto adapter is enqueueing ops beyond the size of the
circular buffer leading to segfault due to invalid ops access.
Fixed by enqueueing ops from head pointer to (size-head) number of ops
when circular buffer becomes full and the remaining ops will be flushed
in next iteration.
