[ Upstream commit af982da9a612295a91f367469f8945c916a20dfd ]

Fix inconsistent IS_ERR and PTR_ERR in cifs_find_swn_reg(). The proper
pointer to be passed as argument to PTR_ERR() is share_name.

This bug was detected with the help of Coccinelle.

Fixes: bf80e5d4259a ("cifs: Send witness register and unregister commands to userspace daemon")
