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.

The current LED beaconing code is unclear and uses the timer handler to
turn off the timer. This patch simplifies the code by removing the
special semantics of timeon = timeoff = 0 being interpreted as a request
to turn off the beaconing.

The LedInfo SMA attribute is redefined to control the LED beaconing
state machine instead of the LED directly. In accordance, we now
return the state of LED beaconing, represented by whether the beaconing
timer is active, instead of the state of the LED itself for SMA queries
Get(LedInfo) and Get(PortInfo). While we are at it, we fix the beaconing
timer control code so that the state of the timer is accurately updated.

Removing QSFP cable should report 'No Local Media' instead of
'Transient' as reported by 'opaportinfo'.
Workaround is to change the state to
OPA_LINKDOWN_REASON_LOCAL_MEDIA_NOT_INSTALLED in cable handler.

With cable still removed, 'opaportinfo bounce' should not cause a
state change to Polling, as reported by 'opaportinfo'.
Resolution is to prevent physical state change from Offline->Polling.

Use a macro to mask lower nibble of OPA_LINKDOWN_REASON* as needed
for offline_disabled_reason.
