Bluetooth: Fix LE reconnection logic
We can't use hci_explicit_connect_lookup() since that would only cover explicit connections, leaving normal reconnections completely untouched. Not using it in turn means leaving out entries in pend_le_reports. To fix this and simplify the logic move conn params from the reports list to the pend_le_conns list for the duration of an explicit connect. Once the connect is complete move the params back to the pend_le_reports list. This also means that the explicit connect lookup function only needs to look into the pend_le_conns list.
