target: Use LIST_HEAD()/DEFINE_MUTEX() for static objects
Instead of
static struct list_head foo;
static struct mutex bar;
...
INIT_LIST_HEAD(&foo);
mutex_init(&bar);
just do
static LIST_HEAD(foo);
static DEFINE_MUTEX(bar);
Also remove some superfluous struct list_head and spinlock_t
initialization calls where the variables are already defined using
macros that initialize them.
This saves a decent amount of compiled code too:
add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-178 (-178)

target_core_init_configfs 898 850 -48
core_scsi3_emulate_pro_preempt 1742 1683 -59
iscsi_thread_set_init 159 88 -71
