bnxt_en: Increase the number of MSIX vectors for RoCE device

Browse source

If RocE is supported on the device, set the number of RoCE MSIX vectors
to the number of online CPUs + 1 and capped at these maximums:

VF: 2
NPAR: 5
PF: 64

For the PF, the maximum is now increased from the previous value
of 9 to get better performance for kernel applications.

Remove the unnecessary check for BNXT_FLAG_ROCE_CAP.
bnxt_set_dflt_ulp_msix() will only be called if the flag is set.
