target/iscsi: Fix double free in lio_target_tiqn_addtpg()
commit a91918cd3ea11f91c68e08e1e8ce1b560447a80e upstream.
This iscsit_tpg_add_portal_group() function is only called from
lio_target_tiqn_addtpg(). Both functions free the "tpg" pointer on
error so it's a double free bug. The memory is allocated in the caller
so it should be freed in the caller and not here.
Fixes: e48354ce078c ("iscsi-target: Add iSCSI fabric support for target v4.1")
