drivers/base/memory.c: remove an unnecessary check on NR_MEM_SECTIONS
In cb5e39b8038b ("drivers: base: refactor add_memory_section() to add_memory_block()"), add_memory_block() is introduced, which is only invoked in memory_dev_init(). When combining these two loops in memory_dev_init() and add_memory_block(), they looks like this: for (i = 0; i < NR_MEM_SECTIONS; i += sections_per_block) for (j = i; (j < i + sections_per_block) && j < NR_MEM_SECTIONS; j++) Since it is sure the (i < NR_MEM_SECTIONS) and j sits in its own memory block, the check of (j < NR_MEM_SECTIONS) is not necessary. This patch just removes this check.
