Linfeng Sun e15b81f602 scsi: target: iscsi: Fix race in discovery auth updates 
Separate configfs opens can concurrently update the discovery AuthMethod
parameter. Both callers may free the same value in
iscsi_update_param_value(), causing a double-free.

Protect the lookup and replacement with the discovery TPG access lock,
as used by the other TPG configfs parameter updates.

Fixes: e48354ce07 ("iscsi-target: Add iSCSI fabric support for target v4.1")
