RDMA/bnxt_re: Remove roundup_pow_of_two depth for all hardware queue resources

Rounding up the queue depth to power of two is not a hardware requirement.
In order to optimize the per connection memory usage, removing drivers
implementation which round up to the queue depths to the power of 2.

Implements a mask to maintain backward compatibility with older
library.
