[PATCH v1] Bluetooth: MGMT: Allow connection rate request as peripheral

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

Load Connection Subrate only issues the LE Connection Rate Request when
connected as central, but either role can initiate the Connection Rate
Update procedure, e.g. a HID device, which is the peripheral, does it
once the HID host requests a HID SCI mode with the HID Control Point.

Issue it regardless of the role.

Fixes: 19129d7037be ("Bluetooth: Add MGMT Load Connection Subrate command")
Assisted-by: OpenCode:claude-opus-5.5
