Bluetooth: MGMT: Clear disabled connection parameters when loading none

Browse Source 
Load Connection Parameters only clears the disabled connection
parameters when it loads more than one entry, so that loading a single
entry can update the parameters of one device without dropping the
others. Loading no entries does not clear them either, though, which is
what bluetoothd does when it starts without stored connection
parameters.

Pair Device adds disabled connection parameters for the device it pairs
with, so these now survive bluetoothd restarts, and new connections to
the device keep using the parameters they were created with instead of
the defaults set since, e.g. the connection interval from main.conf.

Clear the disabled connection parameters unless a single entry is
loaded, as was done for any number of entries before.
