Fix inappropriate shared memory allocation size for clock hand.
Fix inappropriate shared memory allocation size for clock hand.

The memory for clock hand was allocated as
sizeof(pool_fsmm_clock_hand)) which is 8 bytes long because the
variable is declared as:

static int *pool_fsmm_clock_hand;

This is plain wrong. The memory size actually needed is only 4 bytes,
which is sizeof(*pool_fsmm_clock_hand)). In other word, the bug
allocated unnecessary 4 bytes, which did nothing bd for the execution
of program. But a bug is a bug.

Per covery report "1111476 Wrong sizeof argument"
