Call AQ to release any reservation held by this PF on the NVM resource
lock on startup, in order to clear anything that might have been left over from
a previous run.  The lock is only cleared by the requestor calling for it to be
cleared, on power-on, or firmware reset.  This should help limit the need for
rebooting a customer machine if something goes wrong on a firmware update or
some other action.
