cifs: Avoid error pointer dereference
The patch 7d6535b72042: "cifs: Simplify reconnect code when dfs
upcall is enabled" leads to the following static checker warning:
fs/cifs/connect.c:160 reconn_set_next_dfs_target()
error: 'server->hostname' dereferencing possible ERR_PTR()
Avoid dereferencing the error pointer by early returning on error
condition.
