mem: initialise shared locks explicitly

Locks in the DPDK shared memory were not initialised so far.
This is not really a problem as the early_mem_config structure is stored
in the bss section (and so set to 0 by default).
Yet, for consistency, explicitly initialise those locks with relevant
initialiser macros.
