Removed COD check for unbond and UNPAIRED_EVT

PC supporting HID Device would not have Peripheral as
its MAJOR COD. So COD check for major peripheral device was removed
in case of UNBOND and while receiving UNPAIRED_EVT. Additonal checking
is done when virtual unplug evt is received to remove bonding only for
HID Devic with MAJOR COD as Peripheral or if its a locally initiated
VUP.
