Fix event mask setting for a specific 1.2 adapter
One 1.2 Broadcom adapter doesn't respond to the event mask HCI command
at all unless the second byte of the mask is 0xff. Strictly speaking
this is an invalid value because bits 0x02 and 0x04 are reserved.
However, no other adapters seem to mind and using 0xff instead of 0xf9
makes this particular adapter work properly.
