smb/server: fix null-ptr-deref in ksmbd_ipc_tree_connect_request()

See the procedure below:

  ksmbd_tree_conn_connect
    ksmbd_share_config_get
      share->name = kstrdup() // fail
      if (!test_share_config_flag(share, KSMBD_SHARE_FLAG_PIPE)) // false
      // do not check `share->name`
    ksmbd_ipc_tree_connect_request
      strlen(share->name) // null-ptr-deref
