[SCSI] target: Fix match_strdup() memory leaks

match_strdup() dynamically allocates memory and it is the responsabillity
of the caller to free that memory. The following three cases:

drivers/target/target_core_file.c:fd_set_configfs_dev_params()
drivers/target/target_core_iblock.c:iblock_set_configfs_dev_params()
drivers/target/target_core_configfs.c:target_core_dev_pr_store_attr_res_aptpl_metadata()

should be kfree()'ing the allocated memory once it is no longer needed.
It also makes sure to return -ENOMEM if the memory allocation in match_strdup()
should fail.  For target_core_configfs.c, this patch adds kfree()'s around
Opt_initiator_fabric, Opt_initiator_node, Opt_initiator_sid, Opt_sa_res_key,
Opt_target_fabric, and Opt_target_node for the Persistent Reservations
Activate Persistence across Target Power Loss (APTPL=1) token parsing.
