rpmsg: char: Update local endpt address for virtio-rpmsg backend

The rpmsg char driver creates a local end-point when the actual endpt
device is opened. The virtio-rpmsg backend can dynamically allocate the
local end-point address if the endpt creation is done using the address
RPMSG_ADDR_ANY. This is not reflected in the sysfs src file, so update
the stored address with the allocated address in such a case. This
allows the userspace to be able to retrieve the local end-point address
through sysfs.
