RDMA/bnxt_re: Fix max_qp count for virtual functions

Browse Source 
Driver has not accounted QP1 for virtual functions
when fetching device attributes and hence max_qp
count is one less than active_qp count. Fixed driver
so that it counts QP1 for virtual functions as well
while fetching device attributes

Fixes: ccd9d0d3df ("RDMA/bnxt_re: Enable RoCE on virtual functions")
