net/bnxt: fix unnecessary HWRM command

net/bnxt: fix unnecessary HWRM command

During probe, driver issues HWRM_CFA_ADV_FLOW_MGNT_QCAPS command.
But it is not using the command response anywhere which makes the
fw call redundant.

Remove the unnecessary HWRM_CFA_ADV_FLOW_MGNT_QCAPS call to fw.
Remove the redundant flow_flags in bnxt struct.
