securityfs: securityfs_remove should handle IS_ERR pointers
Both of the securityfs users (TPM and IMA) can call securityfs_remove and pass an IS_ERR(dentry) in their failure paths. This patch handles those rather than panicing when it tries to start deferencing some negative memory. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
