RDMA/bnxt_re: Refactor the queue index update

The queue index wrap around logic is based on power of 2 size depth.
All queues are created with power of 2 depth. This increases the
memory usage by the driver. This change is required for the next
patches that avoids the power of 2 depth requirement for each of
the queues.

Update the function that increments producer index and consumer
index during wrap around. Also, changes the index handling across
multiple functions.
