This commit fixes an issue in the test_ccm_mode.c file:

sizeof(data) is used to compute the length of the array pointed to
by the 'uint8_t *data' pointer.

At the same function scope, there is a variable (dlen) that already
specifies the required length, so we use that variable instead of
the 'sizeof' function call.

This issue was not reported by Coverity, although is worth to fix it.

There was no check to see if the head of a list was empty before trying
to fetch the next node in the list. The fix is added to
sys_dlist_peek_next() so that it also return NULL if the node parameter
is NULL, in addition to being the tail of the list.

Since the value is not used until the second iteration of the loop, and
there will be no second iteration if the list is empty, as long as the
CPU does allow reading at address 0, this was not causing any issues.

Our ARC targets did not seem to like that.

Fixes ZEP-1263 and ZEP-1297.

There was a possible race condition when setting the return value of a
thread that is pending, from an ISR.

A kernel function causes a thread to pend, with the following series of
steps:

- disable interrupts
- move current thread to wait_q
- call _Swap

Depending if running on M3/4 or M0+, _Swap will either issue a svc #0,
or pend PendSV directly. The same problem exists in both cases.

M3/4:
__svc will:
- enable interrupts
- trigger __pendsv

M0+:
_Swap() will enable interrupts.

__pendsv will:
- save register context including PSP into the thread struct

If an interrupt occurs between interrupts being enabled them and
__pendsv saving PSP, and the ISR sets the pending thread's return value,
this will happen:

- sees the thread in a wait_q
- removes it
- makes it ready
- calls _set_thread_return_value
- _set_thread_return_value looks at the thread's saved PSP to poke
  the value

In this scenario, PSP hasn't yet been updated by __pendsv so...

The data structure member being used  is character array,
dereferencig this array gives **char instead of the expected
*char type.
