When FM is disabled, and the HFI port on the switch is changed from MgmtAllowed=YES to MgmtAllowed=NO and the link is bounced, FULL_MGMT_P_KEY doesn't get cleared from the pkey table. This also occurs when the QSFP cable is moved from a switch port with MgmtAllowed=YES to a MgmtAllowed=NO port. Clear pkey entry properly. Also, when the driver is loaded and the switch port is set to MgmtAllowed=NO, FULL_MGMT_P_KEY shouldn't be added to pkey table after FM is started. Only set FULL_MGMT_P_KEY in the pkey table if switch port is configured to MgmtAllowed=YES.
