Bluetooth: MGMT: set_mesh: update LE scan interval and window

According to the message of commit b338d91703fa ("Bluetooth: Implement
support for Mesh"), MGMT_OP_SET_MESH_RECEIVER should set the passive scan
parameters.  Currently the scan interval and window parameters are
silently ignored, although user space (bluetooth-meshd) expects that
they can be used [1]
