Due to recent advances in the firmware for Broadcom's
gen p5 series of adaptors the driver code to report
hardware counters has been broken w.r.t. roce devices.

Making a change to match the expectaion of newer firmware
version when stat dma buffer is created. The new firmware
command expects dma length to be specified during stat
dma buffer allocation.

Fixes: 2792b5b95ed5 ("bnxt_en: Update firmware interface spec. to 1.10.0.89")
