[xenial] SRU: [PATCH v2 1/1] Bluetooth: increase timeout for le auto connections

[Konrad Zapalowicz]

From: Konrad Zapałowicz <konrad.zapalowicz at canonical.com>

BugLink: https://bugs.launchpad.net/bugs/1731467

This patch increases the connection timeout for LE connections that are
triggered by the advertising report to 4 seconds.

It has been observed that devices equipped with wifi+bt combo SoC fail
to create a connection with BLE devices due to their coexistence issues.
Increasing this timeout gives them enough time to complete the
connection with success.
