[ Upstream commit 247bc9470b1eeefc7b58cdf2c39f2866ba651509 ]
Fixes: 72abe3bcf091 ("signal/cifs: Fix cifs_put_tcp_session to call send_sig instead of force_sig")
The global change from force_sig caused module unloading of cifs.ko to fail (since the cifsd process could not be killed, "rmmod cifs" now would always fail)
