bnxt_rfs_capable() determines the number of VNICs and RSS_CTXs
required to support aRFS and then reserves the resources.  We already
have functions bnxt_get_total_vnics() and bnxt_get_total_rss_ctxs()
to do that.  Simplify the code by calling these functions.  It is
also more correct to do the resource reservation after
bnxt_can_reserve_rings() returns true.
