Bluetooth: Fix canceling RPA expiry timer

Browse Source 
The RPA expiry timer is only initialized inside mgmt.c when we receive
the first command from user space. This action also involves setting the
HCI_MGMT flag for the first time so that flag acts as a good indicator
of whether the delayed work variable can be touched or not. This patch
fixes hci_dev_do_close to first check the flag.
