RDMA/bnxt_re: Enhance the existing functions that wait for FW responses

Use jiffies based timewait instead of counting iteration for
commands that block for FW response.

Also add a poll routine for control path commands. This is for
polling completion if the waiting commands timeout. This avoids cases
where the driver misses completion interrupts.
