RDMA/bnxt_re: Remove roundup_pow_of_two depth for all hardware queue resources
[ Upstream commit 48f996d4adf15a0a0af8b8184d3ec6042a684ea4 ]
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.
