mptcp: only send RM_ADDR in nl_cmd_remove
The specifications from [1] about the "REMOVE" command say:
Announce that an address has been lost to the peer
It was then only supposed to send a RM_ADDR and not trying to delete
associated subflows.
A new helper mptcp_pm_remove_addrs() is then introduced to do just
that, compared to mptcp_pm_remove_addrs_and_subflows() also removing
subflows.
To delete a subflow, the userspace daemon can use the "SUB_DESTROY"
command, see mptcp_nl_cmd_sf_destroy().
Fixes: d9a4594edabf ("mptcp: netlink: Add MPTCP_PM_CMD_REMOVE")
