ia64: add checks for the return value of memblock_alloc*()
Add panic() calls if memblock_alloc*() returns NULL.
Most of the changes are simply addition of
if(!ptr)
panic();
statements after the calls to memblock_alloc*() variants.
Exceptions are create_mem_map_page_table() and ia64_log_init() that were
slightly refactored to accommodate the change.
