SYSLINK: ipc - fix listmp_sharedmemory list initialization

This patch fixes the initialization of a listmp_sharedmemory
list. A listmp_sharedmemory object is a list of portable pointers, which
are obtained using the sharedregion module. This patch resolves the
list initialization for non-zero sharedregion indices. Checkpatch
warnings are minimized by using a macro for volatile.
