RDMA/bnxt_re: Fix allocation of QP table
Driver is creating QP table too early while probing before
querying firmware capabilities. Driver currently is using
a hard coded values of 64K as size while creating QP table.
This resulted in a crash when firmwre supported QP count is
more than 64K.
To fix the issue, move the QP tabel creation after the firmware
capabilities are queried. Use the firmware returned maximum value
of QPs while creating the QP table.
