[PATCH for-next 01/10] RDMA/rtrs-clt: During add_path change for_new_clt according to path_num

[Jack Wang <jinpu.wang@ionos.com>]

From: Md Haris Iqbal <haris.iqbal@ionos.com>

When all the paths are removed for a session, the addition of the first
path is like a new session for the storage server.

Hence, for_new_clt has to be set to 1.
